"Aggregate and compress CSS files" and "Aggregate JavaScript files" in performance settings, is not working This thread contains the most information I've been able to find about this: #986558: "Aggregate and compress CSS files" and "Aggregate JavaScript files" in performance settings, is not working

I have 2 d7 sites. One is in public_html/ on my server and has no problems. The other is in a sub-directory, and breaks when turning on Aggregation/Compression of css &amp; js files (in admin/config/development/performance ).

When I turn on js performance, my js doesn't work. When I turn on css performance, no css loads on my site in Firefox or Chrome, but does load in Safari. According the the above-mention issue, it's because of Drupal &amp; my server sending compressed info to the browser, which can't decompress it and thus, I get no js or css.

Following a recommendation, I disabled these in my .htaccess file:

#Header append Content-Encoding gzip
#Header append Vary Accept-Encoding


What that did, however, was break some of my css, and load a "skip to content" area in the top of my website (which, if you do theming, you might be familiar with seeing that as a hidden html element that is loaded).

I'm not sure what to do to fix this. I encountered it the first time I built this site, but was using D7-rc1. I rebuilt it hoping new core/module updates would fix it, but this site is running on D7.7 now.

Please help. Thanks.
Well, this issue is ongoing at http://drupal.org/node/986558 . The Drupal-7.9 should have fixed it, and it did fix my css, but I am still having issues with js.

Note: if you have this problem and upgrade to Drupal-7.9 , make 100% sure you replace all of your .htacess files.
