Hello Thomas,

Thank you for reaching out.
The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, and the technologies available on the server. Since everyone’s site, traffic, and theme are different, there is no one-size-fits-all solution.
This is why there are no specific Guides for Woocomerce websites.
1. This depends on what you are trying to achieve. Woocomerce is calling the W3TC hook to purge the cache once something is changed. It also has the option to fragment specific parts of the woo website using ajax to avoid these parts to be cached

2. This depends on a lot of factors, however, Page Caching and Browser Caching are a good start.

3.a) The page is cached once visited. After the cache is purged for any page or all pages, it needs to be visited again in order to be cached if not specifically configured to be Preloaded.
b)c)d) In Performance>Page Cache, the re is a Cache Preload section. Once enabled and added the sitemap URL, upon the first visitation the W3TC starts to preload the entire website using the sitemap and by the Interval set in the Preload settings.
4. No there is no setting for this specific use case as you mentioned, so you can for example create a custom cron to call the w3tc_flush_all(); and after that call the cache prime using wp-cli
wp w3-total-cache pgcache_prime [–start=] [–limit=]

I hope this helps and let me know if you have any other questions.

Tanks!

Hello Stephen,

Thank you for reaching out and I am happy to assist you with this.
Purging the W3 Total Cache – cache all the time is not recommended as it may cause a lot of server resource consumption, naturally, it depends on the website.
There are a couple of things that you can do.
1. Exclude the page where the feed is (in your case /news/) from the page caching by adding /news/ in Peformance>Page Cache>Advanced>Never Cache following pages field.
2. Use Page Fragment Caching – You can check more details in our FAQ about this, but in short, you need to warp this part of the page with the mfunc, replacing the tags and excluding this part of the page from the cache.
3. Setup a custom cron on your server and call w3tc_flush_url($url); every x minutes/hours.

The last one is a programmatic solution that will only purge specific URL instead of pouring the cache for the entire website.

I hope this helps!

Hello Meg,

Thank you for reaching out and I am happy to assist you with this.
In W3 Total Cache settings, depending on the feature enabled, you can exclude specific pages from being cached.
In Performance>Page Cache>Advanced>” Never Cache following Pages”: add /cart/and also in
Performance>Minify>Advanced>”Never minify following Pages”:
Once added, make sure to save all settings and purge the cache.

Let me know if this helps!

Thanks!

Hello Andrew,

I am sorry about the issue you are experiencing and I am happy to assist you with this.
These are the configuration problems. You may be having some other plugins or manual rules that are in conflict with the W3 Total Cache settings and only a couple of tweaks can resolve the problems.
For your first question, and ion order to determine to the source of the problem, can you please disable the settings one by one in Performance>general settings, save the settings and purge the cache after each setting is disabled, and see which one might be causing the issue?

As for the .gz problem, The problem with downloading gzip files is probably that there already is a configuration in the setup that handles gzip files. If you enable gzip in Performance => Browser Cache => HTML & XML, the configuration gets messed up and the browser will download a gzip file in situations like yours. Disabling the gzip option in Performance => Browser Cache => HTML & XML will probably solve this issue.
You can also define W3TC_PAGECACHE_STORE_COMPRESSION_OFF constant that allows not to generate _gzip and similar files. It helps in the cases when the server configuration
doesn’t allow mime type overwrites so cached content ends up with browser
download action.
It’s located in /wp-content/plugins/w3-total-cache/PgCache_ContentGrabber.php line 1191

if ( defined( ‘W3TC_PAGECACHE_STORE_COMPRESSION_OFF’ ) ) {
return $compressions;

}
You just need to add define(‘W3TC_PAGECACHE_STORE_COMPRESSION_OFF’, true);

to the wp-config.php file.
Please let us know if this helps!

Hello Blaženka,

Thank you for reaching out and I am happy to assist you with this.
What this means is that the files and folder permissions on the server are not set as they should in order for the W3 Total Cache to be able to add the drop-in files, create a cache folder and write the .htaccess rules.
Can you please check the files and folder permission, and make sure that their permission is set to the following:
files – 644
folders – 755
Please make sure to check this article for more details.
I hope this helps!

Thanks!

Hello David,

Thank you for reaching out and I am happy to assist you with this.
You are correct when you say that the mentioned CDN provider is not listed in the CDN settings in the W3 Total Cache.
To include this as a CDN in W3 Total Cache takes some time because we are not the only ones that have a say in this.
For the time being, you can use the “Generic Mirror” CDN Type: in the General settings CDN section, and simply replace the URL with the CDN URL to serve static content from the CDN.
I’ll make sure to have a chat with the team and we may reach out to Cloudimage

I hope this helps!

Thanks!

Hello Alex,

Thank you for reaching out and I am happy to assist you with this.
The purge policy is defined in Performance>Page Cache purge policy. There you can find the options where you can specify the pages and feeds to purge when posts are created, edited, or comments posted.
The important thing to know is that the pages are also cached in the Browser Cache, using expires header and cache control header. In the W3 Total Cache, the default value is set to 1 hour.
Can you please try visiting the website in incognito mode or try to hard reload the page and see if the changes are updated when editing or posting a new post?
Thanks!

Hello,

Thank you for your feedback.
You are correct, I’ve checked Safari and yes, the problem seems to appear only on that browser. Other browsers do not have the problem you are referring to when visiting your website.
I’ve noticed that you have Lazyload option enabled, so can you please try to add the image URL to Performance>User Experience>Exclude words: field:
https://congregationofstpiusv.com/wp-content/uploads/2020/03/BpC-PiusCrestOnly-578x1164longer.png
Save all settings and purge the cache and let me know if the problem persists.
Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website on Chrome and Firefox, and I am not seeing the issue you are referring to, I do see that the W3 Total Cache is installed.
Can you please share which browser you are using and if you are still experiencing this problem?

Thanks!

Hello Joseph,

Thank you for reaching out and I am happy to assist you with this.
First of all, if you encounter any issues with the W3 Total Cache, you do not need to restore a backup, you just need to disable specific settings, save all settings and purge the cache and see which setting in Performance>General settings may be causing the problem.
For example, If you have Page Caching, Minify, Lazyload, and Object Cache enabled, one of these settings may be causing the problem you are referring to. When it comes to images it may be Lazyload or Minify (depending on how the image was embedded), and as for the header, Minify is an obvious reason.
Since you have not shared which settings you had enabled before removing W3 Total Cache, I am unable to provide any precise information on what may be causing the problem.
I would advise you to re-install W3 Total Cache, enable the settings one by one, save all settings, and purge the cache after each setting is enabled, (checking the website after every setting is enabled).

I hope this helps!

Thanks!

Hello Susan,

Thank you for reaching out and I am happy to assist you with this.
The only way to determine which feature in W3 Total Cache may be causing the problem is to disable all the settings one by one in Performance>General Settings, save all settings and purge the cache after each setting is disabled and see which one may be causing the problem.
This may happen if Minify is enabled, and specifically, if the option “Disable minify for logged-in users” is not enabled in Performance>Minify.
I can also see that you are using Cloudflare and Sucuri Cache so make sure both of those are cleared once any setting is updated in the W3TC.

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
Can you please try to change the default WP language to English in your WP Dashboard so that W3 Total Cache can use default English and try to Authorize the Cloudflare after these steps?
Let me know if this helps!

Thanks!

Hello Carter,

Hello Mark,

Thank you for your feedback.
So the rules you’ve had for the security headers may be causing the conflict with the W3TC rules.
Can you please drop us a note directly via the plugin in Performance>Support>Bug report so we can check this for you?
Thanks!

Hello Dale,

Thank you for reaching out and I am happy to assist you with this.
In W3 Total Cache, the composer loads the libraries conditionally for AWS functions. AWS SDK for PHP – Use Amazon Web Services in your PHP project
If you are using AWS service, the plugin will load the AWS SDK. Are you using any of the amazon services?

Does the issue persist if you disable the W3TC?
Thanks!

Hello Mark,

I’ve checked your website and indeed the security headers are missing. I can also see that the W3 Total cache is not enabled at the moment.
You can set up the Security headers in the Performance>Browser Cache, and scroll down to the Security headers section. There you can enable the headers you want, and make sure to save all settings and purge the cache.

Thanks!

Hello Harry,

I am very sorry about the inconvenience.
We replied to that W3 Total Cache Premium support request shortly after it was submitted. Not sure how you never got our reply.
I’ve re-sent the email with the instructions to provide additional information and access.
Please let me know if you received the email.
Thanks!

Hello,

Thank you for your feedback.
Can you please disable the database cache if enabled and see if the issue persists?
If the issue is gone re-enable DB Cache and add /wc/v3/* to “Never cache the following pages:” under the “Database Cache” section, save all settings and purge the cache.
I hope this helps.
Thanks!
