I checked the files that are on the server:
The common folder has 5 files in it:
The contents_insert.php file is in the admin folder outside of the common folder which is why I was confused about this. When I installed the CMS, I brought the entire folder over from my local machine using a fresh dowload from webassist to the server via FTP.
Do you think I should upload them again anyway or is this a path issue in one of the pages?
