SharePoint 2013 Unable to create folders

Hi,

I need some help/suggestions with SharePoint 2013 as when I try to create a new folder in a library i get the following message:

“The server was unable to save the form at this time. Please try again.”

Below are the changes tried by me:

– Increasing server memory. Now RAM usage is around 60 %

– Restart the server

– Check permissions

– Restart SharePoint Search Host Controller

– Enable Anonymous authentication on IIS website.

Neither of this worked.

If you have any ideas please reply.

Thank you
