I sort of doubt this could be a file permission problem if your templates don't even save/change (link doesn't change from blue to green) since the templates are saved in the database.
Can you PM me a temporary admin account details so I can have a look?
OK, I created it, gonna PM you now.
Did you fix it Geek?
Geek, please fix this ASAP, you haven't been on in a full day!
I can have a look if you want.
Sorry, been a busy weekend, Just came online, I'll have a look
OK thanks G33k you rock!~
For some reason you had duplicate entries for the master templates (sid=-2) so that there were 2 entries for each template with a sid of -2 where there should be only one. This caused all your templates to not get edited, only those that had been edited prior to this happening were editable.
Removing the duplicate templates fixed it.
