I've inherited a drupal 7.6 site with a broken css (styles were not loading). Here's what I've done so far:
-set sites/default/files, tmp and cache folder to 777. -flushed all caches
When this didn't work, I deleted the /files folder and created a new one which has done the trick.
I'm still getting "The file permissions could not be set on cache/normal/..." in recent log messages. in the cache folder, I'm seeing html being created but there are a lot of "boostfRVyMR" and similarly named files.
Is there other permissions to be changed?
