Cannot edit via Define Pages Editor

I have ver 1.26 installed and I am unable to edit & save pages via Define Pages Editor. I am able to open the desired page and edit it, but after saving the changes, when I return to that page, nothing has been saved.

I have a few mods installed:

affiliates
links
cross sell
time offset
easy populate

Has anyone got any idea if one of these mods is causing the problem, or could someone tell me which files I should check, with a view to sorting this out.

I assume that you have setup an override directory for your copy of these files. I would locate this directory and FTP the files to your PC and look at them with an editor or notepad and see if your changes are contained in them. If they are, then for some reason your override is not being used. Check which template you are using, naming etc.

Normally the admin will not allow saving if you are not editing an override, and will only load an editable file from the template override that you have specified. The admin will indicate the path of the file loaded, check that path also.
