When in designer, everytime I try to edit a dispform (or any form), I get "The server could not complete your request." In the more details section, it says "soap:ServerServer was unable to process request. ---> Cannot complete this action. Please try again. ---> Cannot complete this action. Please try again."
I've tried editing the AAM. I've used the hostname, extended name, even localhost on the server itself and I still get the error. I even went as far as building a brand new web app, and I still get this error.
