For the last day or so I have been unable to view the Customise page for Accounts Form, every other form is fine. When I click on Customise I get the Error: An Error has Occurred Page.
I think the error is caused by an iframe I have on that page, however I cannot be sure as I cannot get in to it to remove and retest. When I go to the Web resource call new_iframe and click the link it get:
HTTP Error 500 - Internal Server Error Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: System.ArgumentNullException: Value cannot be null.

Help me please as I cannot remove or edit anything on the page!!!
Thanks,
