Error while saving

[RMIC]

Hello,

when saving the forms, I get the following error: see attachement.
I use the Forms Designer for onPremise.
How can this be fixed?

Many Thanks!

Best regards,

I looked at the SP logs. The following errors / messages appear several times:

"Unknown SPRequest error occurred. More information: 0x80070005"

"System.UnauthorizedAccessException: Access denied (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)), StackTrace: at Microsoft.SharePoint.SPUser.InitMember () at Microsoft.SharePoint.SPUser..ctor (SPWeb web, SPSecurableObject scope, String strIdentifier, Object [,] "

I do not know where permissions might be missing.

Hi!

At first, please make sure that the solution is deployed to the web application by opening the following page:
{SharePoint Web Url}/_vti_bin/FormsDesigner/FDService.svc

Provide us a screenshot of this page.

Also, please check that you have enough free memory on the server (>5%). If a server has less, all SP services stop working including ours.
