I've started to get some weird errors in my system.log this morning after flushing the cache after uninstalling a possibly problem causing module.
I'm getting a lot of fopen errors showing missing permissions for opening several cache files in var/cache/mage--(numbers)/. After checking all the permissions for all the mage cache folders I noticed all those involving the cache were owned and grouped by root and not the actual website user and group.
Is this supposed to be set this way? or has something gone wrong somewhere along the way? (I'm thinking the latter as, well I'm getting an error, but i don't know if the error is the permissions of the file or permissions of the website user or the fact that this file is trying to be opened)
