Hi, had the same with the 500 Error, so followed the instructions as above, and now cannot access the editor and previous Email Template that was created, now shows nothing. Have reverted code back to original, however this not seem to have fixed the problem. Can someone tell me where I can access this file - protected/modules/docs/models/Docs.php, and update. This will hopefully fix current issue, although I doubt it will rectify the Error 500 issue. Any assistance, guidance greatly appreciated
