OK, I have been using JCE as my prefered editor for literally years on all my Website but have today encountered a strange phenomenon and have now been looking at it for TOO long!
I have created a new user group for "Site Owner" and given all permissions necessary to that group including using JCE as the default editor.
For some reason when editing a module as a "site owner" JCE removes Jpegs! Not so when signed is as superuser...
Both jpeg and jpg are allowable file types withing the default profile - Help! What am I missing?
