I get a "The server was unable to save the form at this time. Please try again" message when I attempt to Edit an item from a specific list using its EditForm. Our SharePoint is hosted via Office 365 so I cant use many of the similar questions already answered here. I used SharePoint Designer to customize the EditForm that is showing the message, but I have done that before for other forms without the error. I can edit items from the list view just fine. This error only happens in the EditForm of the Enrollment list.
Here is a step by step on how I encounter this error:
From a Training Calendar item's DispForm, we click on the "Click Here To Edit A Student's Enrollment In This Session" link.
The javascript behind the link takes us to the EditForm of the Enrollment List. After I click the Save button, the message shows up. Like this...
Any idea as to what is going on?
