To answer the question why you can’t add the theme’s version to your CSS file, it’s likely because the Version property of $theme is private so you cannot access it directly, but you can access it through the public get function. Try this instead: $theme = wp_get_theme(); define(‘THEME_VERSION’, $theme->get(‘Version’)); You also don’t need to add … Read more
How I define max cache time to Google Fonts installed on my site
I figured it out. There’s a SiteGround Optimizer plugin that apparently does caching for the site. It’s bizarre. I deactivated the plugin, then reactivated it and all my changes appeared on the site when logged out. So weird.
There is no general method of doing this that works for all plugins. And no generic WordPress steps to take or officially supported paths. Each plugin requires a unique answer and solution that is very specific to that plugin. Some plugins may not support this, while others already depend on doing this. You would need … Read more
It’s hard to answer this given that each site is most likely different and each server is also configured differently. If these sites are individual WordPress installs then 1GB /30 sites is normal, an absolute bare minimum per site would be 32MB for apc.shm_size, this equals 960MB with no overhead. 32MB is in my opinion … Read more
Sorry for this but I found out in the end that my ISP was doing some kind of caching on their end. Had to phone them and explain the issue. When they started seeing it too, I kwen the problem was with them. Thanks for all the comments btw.

As all and any artifacts, constructed from versioned data, these files can and have be excluded from versioning – everybody will be able to rebuild these files from versioned … Read more
A couple of thoughts for you. –Are you creating a new theme from scratch? If so, drive on. If you are modifying an existing theme, changing another’s theme style.css file can be trouble. If you are modifying an existing theme, stop what you are doing, and spend 30 (yup, 30!) minutes to learn how to … Read more
Adding custom variables(query strings) to static resources doesn’t affect caching at some of the levels you’ve listed above: WordPress plugin caching Webserver software caching PHP opcode caching MySQL caching WordPress query caching Several more etc. All of these don’t cache static resources(js, css and so on) but rather cache the output of application codes at … Read more
Turn off your cache, and the variables should work as expected. Caching saves copies of your output and doesn’t execute the code every time the page loads. As a result, server variables might contain information form a past page load as opposed to a current page load.
