One of our business user is facing issue in MOSS 2007 site. He couldn't able to edit/check-in/check-out documents in the document library even though he's having 'Contribute' permissions to the library.
It didn't even show any error message. The user is using IE11 for his operations so I suggested to turn on 'Compatibility View' and check the same. But it didn't work out.
Is there any other possible solution to resolve this issue.
