We are having a My Site in our SharePoint environment,for every one having their own personal site,in that site when they tried to edit SharePoint profile information we are getting issue
“There was an error processing the request my site in SharePoint”
We are having multiple web applications and one Managed Meta data service application.
Web application 1: http://dotnetsharepoint.com -> connected to Managed Meta data service and all service applications connected with default proxy group.
Web application 2: http://mysite.dotnetsharepoint.com -> not connected to Managed Meta data service and all remaining service application connected with custom proxy group.
Navigate to Central admin->Application management ->Configure service application associations
There we can able to see all the web application connections connected to Application Proxy Default/Custom.
In my case “my site web application” is connected to “Custom proxy group”, click on the custom and check the check box of “Managed Meta data service application” and click ok.
Now navigate to my site and we can able to edit and update the profile information without issues.
