Hello,

Thank you for your feedback.
Can you please disable the Image service in the Performance>Extensions, save all settings and purge the cache?
Once this is done, check your website. Re-enable the extension, and without converting all images at once, go to the Media library and try to cover the single image while checking the network tab if any of the ajax requests are throwing 404.

Thanks!

Thank you for your feedback.
Well, I’ve checked the website and all the files are gzipped.
can you please share what is the other method you are using for gzip? Also, share the files(pages) that are having the problem, so I can check that also.
I’ve added this plugin, added the page to Customize “No Access” Page and this page was not compressed with gzip or br.
Is this the plugin you are referring to?
Thanks!

Hello,

Thank you for your feedback.
I’ve checked your website and I can see the Content-Encoding: gzip header, which means that even if the W3TC is disabled, something is setting the gzip compression on a server level or any other plugin that you may be using.
Check if the gzip compression is enabled on a server level with your host, and make sure that zlib.compression is disabled also.
Once again, something is setting gzip compression and it’s not related to the W3 Total Cache.
Thanks!

Hello,

Thank you for your feedback.
So to clarify, When W3 Total Cache is active, regardless if any option in the plugin is active or all are disabled you are still experiencing the problem?
If this is the case, I am sorry but without knowing more about the server configuration and the website URL, I cannot share any specific instructions on how to Remedy this.
The reason for this is that if the W3TC is installed and active, and all the settings are disabled, it means that the W3TC does not have any impact on your website.
The W3TC uses the .htaccess in the root folder of the website. If the gzip compression is enabled for the HTML files for example you will have the following rules within the W3TC Browser cache rules block:

<IfModule mod_deflate.c>
        AddOutputFilterByType DEFLATE text/html text/richtext text/plain text/xsd text/xsl text/xml
    <IfModule mod_mime.c>
        # DEFLATE by extension
        AddOutputFilter DEFLATE js css htm html xml
    </IfModule>
</IfModule>

You can also see the content-encoding: gzip header.
Tanks!

Hello Christina,

Thank you for reaching out and I am happy to assist you with this.
Just a quick note, there is no Premium support menu in the W3TC options, there are additional Premium support options which are “Do it for me” solutions.
As for the issue you are experiencing, the continued processing and the fact that the Support page is empty is suggesting that some other plugin or server configuration is restricting API calls that the W3TC is using to fetch the Support form and to cover the images to webp.
Can you please check if you have any kind of security plugin or some custom .htaccess rules that may be interfering with the calls W3TC is trying to make?
Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
The W3 Total Cache has the option for Gzip and you can find this option in Performance>Browser Cache, in the General box for all types of files or you can enable/disable it for individual files type.
If the Gzip compression is disabled, then the W3 Total cache does not compress any files.
You can check this by checking the .htaccess file for any mod_deflate-related W3TC rule.
Can you please share your settings and also share the URL so I can see if the files are indeed gzipped?
Thanks!

Hello,

Thank you for your feedback. I forgot to mention that the in-depth Audit of your website is Premium support. This is because this includes the Audit of all the plugins, servers, and impact of the 3rd party resources, and for that we need access.
So the optimization of your website may be out of any plugin’s hands and possibilities.
I hope this clarifies my reply.

Hello Saif,

Thank you for your feedback.
I’ve removed the license key as this is a public forum, and as I can see the license key is not yet applied to your installation.
The configuration depends on a lot of things. 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 and traffic and theme are different, there is no one size fits all solution.
We are going to perform tests on your website, and provide you with some tips and guidance on what you need to do or change in order to achieve the best performance for your website.
The Caching method selected for the Page Cache minify and DB Cache are good and recommended in most cases. For Object Caching and Database Cache, it’s not recommended to use Disk-based caching so I would advise either using memory-based caching like Memcached or Redis, or not using it at all.

Object Cache allows getting data from the database more efficiently. Its purpose is similar to what Database Cache does. But compared to Database Cache, Object cache is more efficient as it allows the process of fewer requests.

As a rule of thumb, Object Cache is not worth using on shared hosting for the same reason as Database Cache, i.e. database is often not the performance bottleneck, but disk input-output operations.
However, like Database Cache, it can be beneficial to use if you are on VPS or a dedicated server, get a lot of traffic, and have a lot of comments. Also, if you know that database is the bottleneck of your website performance, then Object Cache (like Database Cache) is beneficial to use. But in this case, it’s recommended to use Opcode, Memcached, or Redis options as mentioned previously.

FSD CDN is great but sometimes not necessary. It depends on how good is your server and whether you are serving the website for local or worldwide users.

Thanks!

This is related to the W3 Total Cache, however, it’s also related to your server resources need for the W3 Total Cache to do its job.
The Error means that the PHP memory is exhausted and reached the limit of 40MB in your case, and what you need to do is to increase the memory limit.
Its recommended using 128MB or 256 MB
You can find out more on how to achieve this in this article, and if you are unsure about this, please make sure to reach out to your hosting provider.

Let me know if this helps and if you have any other questions.

Thanks!

There is no difference between the Free and Pro versions of the W3 Total Cache when it comes to setting expires header or cache control header.
To do this, you need to enable Browser Cache in the Performance>General settings and save all settings Then go to Performance>Browser Cache and you can enable “Set Expires header” and “Cache-control header” in the General area or for individual files like HTML&XML, JS&CSS and Media&Other files
Let me know if this helps and if you have any other questions.
Thanks!

Hello John,

Thank you for reaching out and I am happy to assist you with this.
W3 Total Cache Pro unlocks the additional features in W3 Total Cache settings, which can improve the speed and performance of the website, depending on what the website needs in terms of improving the performance.
One thing that I can suggest is to purchase our premium support option in Performance>Support – Performance Audit.
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 and traffic and theme is different, there is no one size fits all solution.
This service also takes into account the idiosyncrasies of Web Performance Optimization (WPO) in a WordPress context. This means that WPO best practices have to be modified for WordPress because of how the application operates. The number of counter-intuitive realities could fill a small book.

This means that the best configuration for your site might not involve enabling minify, database caching, and other things that you might expect. As a matter of fact, it can actually hurt performance by implementing features for the wrong situation.

The deliverable with this service is a faster site. It’s impossible to predict the extent to which our work will improve performance (especially true for code we didn’t write running on servers we didn’t build), but our promise is that we’ll do our best.

Additionally, we’ll send along a performance report that outlines the improvements, recommendations (if any), and what else we can do to help you reach and exceed your performance goals. There are many ways that we can help improve performance, you should think of W3 Total Cache configuration as the starting point for optimizing your site.

Upgrading to W3 Total Cache Pro makes this work even more effective, as we’ll have additional features to utilize in delivering the best possible results. It’s best to upgrade before placing your order since we can do this for you, and you can upgrade right in the Dashboard on any W3 Total Cache page.

Thanks!

Hello,

Thank you for reaching out and I am happy to assist you with this.
Can you please share more information on how W3 Total Cache settings do not affect your website and what settings are enabled In the General settings?
As I can see you have a lot of customers (or some other plugin) CSP headers and I can see that the Lazyloading is working as expected.

Thanks!

Hello Jonathan,

W3 Total Cache supports the usage of Redis as a memory-based option. So yes Redis is naturally supported.
In order to use Redis in W3 Total Cache, and since W3TC only recognizes the PHP modules, you need to install PHP Redis module
I hope this helps and let me know if you have any other questions.

Thanks!

Hello Berto,

Thank you for reaching out and I am happy to assist you with this.
You explained the process, and yes, this is correct. Once the Page Cache is purged, the cached files get the _old extension, which means that those are expired files. This is actually done to prevent loading the cached page, and force updating the page cache. The Garbage collection interval: in Performance>Page Cache>Advanced is used to remove all the _old files from the cache directory in the specific time set, which is triggered by wp_cron.
By default, the Garbage collection interval is set to one hour (3600s) and after the cache is purged, the _old files will be removed in that interval.

I hope this clarifies things and answers your question.

Thanks!
