Also the users have said they have started getting an xml error when they use the pages/content area of admin and I have started getting the same error when I  try to view child pages

the error is

Code: Select all

Error: the xml response that was returned from the server is invalid

I have installed loads of sites with cmsms ad never had any problems, would be very grateful of any help. Thanks.

Seems it was all to do with the language files, sorted. Thanks

You have/had been hacked, make sure you are using at least CMSMS 1.2.5...
