Facing problem with automated Cache Purge

Dear Developer,
Hope you are doing great!

I am using W3TC plugin with Cloudflare Extention especially for HTML caching. I am facing problem due to aggressive cache purge issue.

For example, when I edit any comment and update it, then the only page cache should be purged. Right?

Why this plugin purge even static file such CSS, JS, images, etc even which is not going to change far future with its specific file name.

I often get a comment and update my site in a day. So, whenever I check header response of my static resources, it often shows cf-cache-status: Expired. But I want maximum HIT response.

Clearly, means I am losing performance benefits. Please fix this problem.

Also, could you please explain to me what is this “Widget statistics interval: Last 30 minutes”

Thanks & Regards,
Gulshan

Dear,

I’d like to know how to specify my redis server’s socket path instead of IP and PORT.

Using: unix:///var/run/redis/redis.sock or /var/run/redis/redis.sock fails.

Kind regards,

No way to hook into the config

I am still having an issue finding a way to hook into the config.
Does anyone know how to programmatically set a config setting.
ie. pgcache.memcache.servers

I found this hook “w3tc_save_options”, but it will only run when saving the options.

I am hoping for a define() that I can put into the wp-config.php

ie.
define(‘WP_CONFIG_pgcache.memcache.servers’, ‘1.1.1.1:11211,2.2.2.2:11211’);

Our Memcacher Server IP will change periodically due to power outages or reboots and will get a new IP assigned to it. I am able to get the current IP with php.

Thanks

Where did the “FIle Management” Minify Option go?

Hi all,

I was making use of a feature in W3 v0.9.5.1 but it seems to have disappeared in v0.9.5.4.

The options were called ‘JS File Management’ & ‘CSS File Management’, located in Minify > JS & Minify > CSS sections of the settings.

Here’s what it looked like:

Does anyone know where I can find this setting or something comparable in v0.9.5.4? Thank you!

Hi,

We have some IE specific styles that get applied via the body_class() function. How can we exclude the body_class() from the cache so that we always get accurate/fresh class names on each page load?

Serving cached pages after user logs in

Hi

I have a subscription website, where users can see restricted content after sign in and subscribe. If user is not logged in, the content is served partialy, with an error message.

Problem is, if the user is reading some page without login, then see this error and then login on “my account” page, when he comes back to the page he was reading before, the content served is cached with the message error, as he was not logged in (but he is).

If this user force his browser to flush cache using CTRL + F5, the refreshed page is correctly served.

So… I think maybe I’m having some issue with browser cache.

How can I force browser cache to clear after user logs in or how can I force W3TC or my browser to serve an uncached page if user is logged in?

My browser cache configs:
– Set Last-Modified header
– Set W3 Total Cache header
– Enable HTTP (gzip) compression
– Prevent caching of objects after settings change
– Don’t set cookies for static files
– Do not process 404 errors for static objects with WordPress

In page cache we are using: “Don’t cache pages for logged in users”.

I’m also using Cloudflare.

Database Cache when Object Cache through Redis?

Hi,

I am using Redis and the plugin “Redis object cache”. I obviously have Object Cache disabled in W3TC but my question is, should I also disable Databse Cache?

I have searched for hours and can’t find a single article, blog or anything that explains if these two are mutually exclusive? Object Cache sounds like it includes Database Cache plus other things, but I may be wrong?

not recognizing memcached extention after EasyApache Upgrade

Hi,

I have W3TotalCache installed to several websites sitting on a WHM (cPanel) server.
It was recently upgraded from EasyApache 3 to EasyApache4, and some of the PHP modules were changed.

The W3TC stopped recognizing the memcached extention in on all my websites following this upgrade, and I was asked by the hosting company to provide which PHP Extensions W3TC requires, especially for mem_cache .
If it matters, the said WHM server is running the following PHP versions: 5.4, 5.5, 5.6, 7.0, 7.1.

Any farther information will be very appreciated.

Minification causes CSS and JS files not to load

Replies: 0

Hi, I’ve been using W3TC successfully for years. But I recently switched to A2 Hosting, and now when I try to use W3TC minification (adding files manually one at a time), the CSS and JS files completely fail to load if added to the minification lists. For example, all styling disappears, or files that depend on the jQuery library (such as slideshows) do not function correctly even if I put the library in <head> in blocking mode.

I’ve spent most of a day troubleshooting this, and I even contacted A2 Hosting to see if they know of any issue on their end. I did try disabling all the minification options that come with A2’s built-in “A2 Optimized” so as not to conflict in any way with W3TC, but this did not help.

Has anyone run into an issue where minified files completely fail to load?

Thanks for your help,
Suzanne

How do I go about configuring Azure storage. Can I do it from the command line?

I’m using W3 Total Cache with Cloudflare and Max CDN.

I’m transitioning my website to SSL.

I deleted the pull zone in Max CDN and created a new one with SSL.

I updated the CNAME record in W3 Total Cache in my WordPress installation from the old CNAME to the new one using shared SSL.

It works fine in the home page. Images are load nicely from the new CNAME with the SSL.

But it doesn’t work if I navigate to other urls in the site. Images are loaded from the OLD DELETED CNAME!

How can this be?

Of course I’ve purged all the caches.

Can you please help me? This is urgent because my images are no longer loading 🙁 🙁 🙁

Thanks a lot

Getting wrong User Data and Products in Shopping Cart

Replies: 0

Hello,

we are running a small shop and recently started using W3TC, which speeded up the site a lot (thanks!).

Unfortunately, since using W3TC we receive messages from users that they have other people’s Address Details in their Checkout page, and also sometimes unordered products already present in their Cart.

We have deactivated page cahing completely then. But for performance reasons I think we should try to re-activate it and exclude some pages from page caching. There is a box for that. But I am unsure if I get the syntax right.

If I want to exclude http://www.myshop.de/checkout (url rewritten of course)…what must I enter into the box?

checkout
/checkout
http://www.myshop.de/checkout
http://www.myshop.de/checkout/

?

One exclusion rule per line, right?

Thank you very much!
