Hello Jody,

Thank you for reaching out again.
W3 Total Cache is the caching plugin. W3 Total Cache(W3TC) improves the SEO, Core Web Vitals, and overall user experience of your site by increasing website performance and reducing load times by leveraging features like content delivery network (CDN) integration and the latest best practices.

W3TC is the only web host agnostic Web Performance Optimization (WPO) framework for WordPress trusted by millions of publishers, web developers, and web hosts worldwide for more than a decade. It is the total performance solution for optimizing WordPress Websites.

Thanks!

Hello Louise.

Thank you for reaching out and I am happy to assist you with this.
With W3 Total Cache you can preload the cache, of course, however, it cannot be done for specific user roles.
The reason for this is that the Preload is based on the sitemap URL, which you need to add to the Cache Preload section in Peformance>Page Cache.
In any case, it’s not recommended to cache pages for logged-in users to avoid sharing any private and sensitive information which may be cached.
Once the website is preloaded with W3 Total Cache Cache Preload, those can be served for logged-in users also, however, it’s best to exclude specific pages from the cache like /account/, /checkout/, /cart/
The prices should be dynamic and firing with ajax, so those should not be cached if this is the case.

Once again, it’s not recommended to cache pages for logged-in users, and I hope I explained the reason for this.

Let me know if you have any other questions.

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website and as I can see all the Images coming from your server are converted by W3 Total Cache and served as webp, all other images coming from the external server https://ae01.alicdn.com/ are not converted since W3TC cannot handle those images as they are not on your server.
“Failed to retrieve a response. Please reload the page to try again.” this may happen on some occasions, and this depends on how many requests is the API server handling at the moment. The ajax requests you are trying every 10 sec or so and yes, this may cause the server resources to hit the limit on occasion.
Please also note that the Pro users have the advantage when it comes to image conversion, and those requests are favored by the Server.

I hope this helps!

Hello Daryl,

Thank you for reaching out and I am happy to assist you with this.
As I can see that the images are converted:
https://www.britishcolumbia.ca/wp-content/uploads/Community-Vancouver-iS471390003-TIBC-e1643405558903.webp
https://www.britishcolumbia.ca/wp-content/uploads/tibc-website-hmpagemap-830x450px-newblue.webp

When you find that your original image has been converted to WebP, but other image sizes are missing WebP versions, you may need to double-check that your WordPress environment supports the WebP format.

While the original image is converted via our API service, the different sizes (e.g. Large, Medium, Thumbnail) are created by your own server. For this, you must have WordPress 5.8 and the appropriate libGD or ImageMagick package available on your server.

To check if your WordPress environment supports WebP, navigate to Site Health > Info > Media Handling and double-check that WebP is listed in the supported file formats for the library shown in the Active editor. If you find these are missing the WebP extension, consult your system administrator to set up the correct packages.

Please make sure to check this and let me know if you have any other questions.

Thanks!

Hello Piotr,

W3 Total Cache Pro licenses are valid on a per-install basis, meaning you need one for every WordPress instance you run. If you have three separate websites, you will need three licenses in total—one for each site. If you have five sites in a WordPress multisite instance, you need just one license for all five sites. If you are interested in bulk licensing, please email us for more information.

Hello,

Sorry for the late reply I was trying to replicate the problem.
By default, minify should not be enabled for logged-in users so you should disable this option.
This is a very peculiar use case, and honestly, I’ve never had a chance to encounter this kind of issue.
As for The unsuccessful transfer queue, you should click the button near it and try to re-upload files.
if works – it’s a temporary issue linked to server resources.
You are using CDN Type: Push, and this means that invalidation of the files needs to be done manually.
The Only purge CDN manually option, if enabled is there to ensure the CDN purge is done manually due to the huge AWS bills for invalidations.
You can always submit a bug report in Performance>Support.

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
To confirm, you are also using the W3TC CDN feature to upload files to CDN, or are you using some other plugin for this?
If you are using the W3TC CDN module, can you please check if the option “Host minified CSS and JS files” is enabled in Performance>CDN>General?
Is the problem with both CSS and JS files or only CSS files are not being uploaded to the CDN?
Since the path of the files is modified (normally it should be wp-content/cache/minify/), you can try adding the path to the Custom file list: in Performance>CDN>Advanced.

Thanks!

Hello Stacey,

Thank you for reaching out and I am happy to assist you with this.
Please understand that the number of requests can be huge depending on the time of the day, and also note that W3 Total Cache Pro users have an advantage when it comes to converting images. This is why at some point conversion can take a bit longer than expected.
We are working every day to improve this process to be faster for all users.
You can safely turn the Image service off in Performance>Extensions and deactivate the feature.
Once deactivated all images will be prevented back to original state

I hope this helps!

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
For this, you can use Page Fragment Cache as a method in W3 Total Cache to exclude specific parts of the page from being cached.
With this method, you can wrap the PHP code with (replacing the PHP tag). This will ensure that this part of the page will be excluded from Page cache.
Please note that this is only available when using Page Caching Method Disk, or Memory-based caching methods like Memcached or Redis.
You can check more about this on our FAQ page
The best method is to fire these parts with Ajax, which will automatically bypass the cache.
Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
W3 Total Cache does have the ability to cache all products and categories. Depending on your store configuration, some templates may have define('DONOTCACHEPAGE', true); constant which is used to prevent caching.

I hope this helps!

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
I’ve checked your website and I can see that W3 Total Cache is enabled, specifically, Page Caching is enabled as I can see, and Browser Cache.
I checked the mobile version using Android and iPhone, and with different browsers and I am not seeing the issue you are describing.
Can you please confirm you are still experiencing the problem and can you please share the specific page you are having issues with or is the problem random?
Thanks!

Hello,

Well, this is very strange.
The Cloudflare support refers you to us, even tho the problem started once you started using Cloudflare. And as we confirmed, you have not been experiencing the problem only with W3TC, and this was solved by excluding the pages from the cache.
I am not quite sure why this is happening when you are using Cloudflare. The best thing in my opinion would be to move the login to a /login/ page or /account/ page and not use the popup since it the problems you mentioned may appear.
I hope this helps!

Hello Karin,

Can you please reach out directly to us via the website contact form and provide the information about your account so we can find the subscription?
Thanks!

Hello,

As I’ve mentioned in the email via the W3 Total Cache support channel, and in the other forum topic, I’ve reset the active URL activated on 2022-07-11

Remove the license key from Performance>General settings, Licensing sub-box, license field and save all settings. Re-enter the license, verify the license with the “verify license button” and save all settings.

W3 Total Cache Pro should be active after these steps!

Thanks!

Hello,

Thank you for your feedback.
Let me know if the problem persists with the default W3TC Browser Cache settings.
Also, make sure to check and configure Cloudflare Page rules and exclude the page from the cf cache.
Thanks!
