yap i did...
i did use f12 to check for errors.... and error no1 says unable to execute codemirror.js and i checked for the file on my server and it wasn't there.
i uploaded another copy of the Codemirror.js but after reloading the items inside /applications/core/interface/codemirror
it disappeared again.... i did over again... but no way..
So What did i DO to solve the Problem ?
i moved all the files inside my domain folder to a separate folder and removed the domain form the server but first i deleted the domain folder. and after then moved the files back to the domain folder..
so when i uploaded the codemirror.js file.. it stayed and i was able to edit my templates again.
