Activated system cache results in naked CSS

[bmoore622]

I'm working with https://abpnews.com/ and have a two-layer problem. First, index.php is causing CPU usage to climb very high. I'm on a WiredTree VPS with 8 cores/3GB. Server load bounces between 5.5 and 9.5. Joomla debug reports over 500 queries being run on home page load. I've disabled any unnecessary plugins/components to lighten the load, but still no luck.

To alleviate some of the load on the server, I've turned on global caching and the system cache plugin. When I do this, however, after 20 minutes or so, the site loads as if there is no CSS to style the page. I get the same result with JotCache.

Has anyone experienced similar issues, particularly with the caching problem described above?

EDIT: Here is another clue... when system cache and debug are both turned on, the site works as expected. With system cache on and debug off, I get naked CSS.

This is a new one for me.

Your web server error log and/or browser console may give some clues, e.g. what error code is being returned when it requests the CSS, etc.

Here's how to open your browser's console:

Not enough information to guess about the CPU load issue, but if you post the results of the Forum Post Assistant, that may help. You should also look at the Warnings and Database tabs under Extension Manager. Also make sure the live_site option is blank (empty quotes) in configuration.php.

Hopefully it's something simple like a redirection loop due to a tiny typo in .htaccess or something.
