Odd/Random Error

Was working on my site - without making any changes elsewhere - and after trying to save a doc I got the following error:

Warning: fopen(../assets/cache/siteCache.idx.php) [function.fopen]: failed to open stream: Permission denied in /home/sites/www/web/dev-site/manager/processors/cache_sync.class.processor.php on line 226
Cannot open file (../assets/cache/siteCache.idx.php)

Any ideas?

Solved. It was a permissions error. Cannot understand how this changed however.

Keep a close eye on this; hackers often try to access the cache files if they can get access to an entire server, and sometimes unexpected changes to permissions or ownership can be an indication of a security breach in the server.

What permissions should the cache files be?

That depends on your server configuration. If you are not using some kind of suexec, you’ll need 777 on the directory and 666 on the files. Otherwise, 755 and 644 are common.
