The watchdog reports do not show the issue, and I believe it to be a permission error or caching error with Apache2, but unsure. I have tried: clearing cache, searching for a relevant php file with unreadable permissions, and looking over .htaccess files for anything out of the ordinary. I may have missed a few php files but I am looking for confirmation that I am heading in the right direction.
I will probably end up asking the web platform IT people for help if I can't find an answer, but anything at all will be greatly helpful. Thank you.
