Are they any kind of recommended server settings? It appears several CSS and JS files aren't being minimized. Some files aren't being fixed with a cache expiration date as well. After installing the plugin I did receive a slight boost to gtmetrix scores, but not everything appears to be implemented. It's as if W3 Total Cache is only half-working.

3Lancer on "[Plugin: W3 Total Cache] jQuery minify when using RevSlider"
@Destac - Thanks for your reply. You are correct.
I was planning to swap Wordpress local jQuery with a Google hosted one and async it. However, logically jQuery should be loaded early as possible incase the webpage has document onload using it, etc. It will probably just delay it's wait longer or run into issues. I've moved it back out.

When you update the file(s), why don't you just use the W3 cache Empty option?
Logged in under your WordPress Admin, on any webpage, at the top you have "Performance" with a dropdown list "Empty All Cache" or "Empty Modules > Empty Page Cache".
Adding version control parameters to JavaScript and/or CSS tends to just slow you down.
If you do want version suffix, try the option under W3 cache called "Prevent caching of objects after settings change" I believe? I haven't tested it myself but this might be what you are after?

When I try to install W3 Total Cache, It is not showing install option. Instead it is showing not supported by your system due to performance and security concerns. Can any one tell how to install it

You can't its blocked by your webhost. You probably have managed WordPress hosting so it and other caching plugins are disabled.

Set it to manual minify and add the files manually.

dhuyvetter on "[Plugin: W3 Total Cache] W3TC compatibel w/ HHVM? ob_callback() warning"
In my HHVM error log I get this warning:
nWarning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a reference, value given in /var/www/mysite/wp-includes/functions.php on line 3549
I saw this workaround on https://wordpress.org/support/topic/should-i-be-worried-warning-parameter-1-to-w3_plugin_totalcacheob_callback?replies=8#post-7981181 to remove the ampersand in that function call. But I don't want to manually change something on a live version of the site, when the next update to the plugin will just overwrite this.
I'm also getting other weird behaviour of the plugin, not sure if it is related. Just want to check: Is W3 Total Cache compatible and tested with HHVM?

John O on "[Plugin: W3 Total Cache] Making sure cache updated for custom taxonomies etc"
Hi,
I am running your excellent plugin on a client website I am building, and am expecting them to perform a large content update very soon. While testing this week I noticed that if I add/edit a custom post, while the post itself it purged from the cache, the custom post taxonomy page does not automatically update - I have to purge the site cache and refresh the page to pick up new items in the list.
Looking in Page cache settings I spotted a section called "Purge Policy" - which item in here will purge custom taxonomy menu pages? Is it "post terms" ?
Thanks in advance.
John

Unfortunately disk enhanced page caching will not function without custom rewrite rules. Please ask your server administrator for assistance. Also refer to the install page for the rules for your server.

Hello,
I would appreciate some assistance. I would like to know if there is a way to restore W3 Total Cache back to it's original default settings. I had everything working OK, but then made numerous tweaks that made things worse. I would like to start everything all over again.
Thank you very much for your help!

You only need to remove the & in front of the $buffer. This works for all of the live sites that I have tested it with.

These users obviously had old versions of html and css/js in their browser cache, so actually a "Browser cache" problem instead of a "Minify" problem.

Yes this is correct but I want with w3 to be able to force download of the new css files

georgerickards on "[Plugin: W3 Total Cache] Avada Fusion Slider images not caching - W3TC"
I'm working on a website for a customer and they've been having issues with page load speeds. We've got it working very well now thankfully, however we've noticed that the 4 slider images in the Avada Fusion Slider are being loaded each time the page is reloaded rather than bringing them from the cache.
Is this just simply how it works or have we got a setting wrong somewhere?
All other pages and content are caching correctly.

aldemarcalazans on "[Plugin: W3 Total Cache] Unnecessary RewriteBase line in .htaccess cod"
Hi Frederick.
I took a look in the new version of your plugin, and I noticed that it includes unnecessary "RewriteBase" lines, along .htaccess file. They are useless because, in a situation like that, only the last definition (read "WordPress definition) will prevail over all others.
Suppose we have two files: message.html, with the text "Hello!" and /subdirectory/message.html, with the message "Goodbye"
In the code below, the result will be a "Goodbye" (and not "Hello"), despite the fact we have a RewriteBase pointing to the root folder, before the RewiteCond. The reason: the second RewriteBase in the code will overwrite the first one!
RewriteBase /
RewriteCond %{REQUEST_URI} ^/say-me-something/$
RewriteRule ^(.*)$ message.html
RewriteBase /subdirectory/A better approach would be checking the WordPress definition and then define the redirection URLs based on it. I guess your plugin already does that (I did not identify any bug in the redirections), so the notes here refers only to the elimination of useless line of codes.
