I changed the FileField to FileIFrameField, now the upload works, but whenever i try to save the page i get: Error in Ajax evaluator on line 974: invalid flag after regular expression
The document is actually being saved, but the error message is really annoying.
Could somebody please help me resolve this? Or maybe tell me where this error comes from? Is there some sort of Error-Log with a more detailed description, since i really don't have a clue where to start debugging.
