I have a SharePoint 2013 Farm with 4 WFEs and 3 App Servers which has one web application with the migrated content from SharePoint 2010. (Migration done using the content database detach attach process).
All content has been restored successfully and most of the functionalities are working as expected.
when trying to add a new folder in any document library in site collection level or any of the sub-sites it throws
"The server was unable to save the form at this time. Please try again."
I have tried all the solutions and workaround suggested across the blogs like ,
- IIS reset ,
- Restarting Search Host Controller service
- Enabling/Disabling HTTP Activation feature in .Net 3.5 and 4.5 in Server Manager
- Restarting all the servers in the farm
- Creating a custom permission level with "Use Remote Interfaces - Use SOAP, Web DAV, the Client Object Model or SharePoint Designer interfaces to access the Web site."
in logs i'm getting messages related to "access denied to /_vti_bin/client.svc?ProcessQuery".
but still the issue persists can't able to get rid of this issue.
Need our SharePoint techies expertise to solve this.
