Cached files returning 403

I’ve just installed the latest version of SuiteCRM and most of it is working except for some of the javascript because it throws errors like these:
Failed to load resource: the server responded with a status of 403 (Forbidden)
http://xxxxxxx/suitecrm/cache/jsLanguage/en_us.js?v=qwD0Nm6JaeZdLCd_tcdziQ Failed to load resource: the server responded with a status of 403 (Forbidden)

I’ve checked the permissions and they’re 755, what else do I need to do?
Thanks.

I also installed the latest version and got into trouble with cached files. I got a different error, for a different file, but anyway, I solved it by deleting the entire cache directory and SuiteCRM re-created it.

Make sure you have a complete backup of your system before attempting this, I can’t guarantee it’s safe. But for me it worked great. SuiteCRM was very slow in the first minutes, as it recreated the cache, then went back to normal.

Just an update - deleting the entire cache is NOT a recommended action. But some parts of it, yes. Google for “SuiteCRM delete cache” and you will find a couple of posts about this.
