I have an internal sharepoint site with multiple lists and permission groups. Different permission groups have access to different lists. All lists have unique permissions to with specific permissions groups.
Users in all the permission groups have contribute rights.
The problem faced is that users are able to access the list but is unable to upload documents to the list. Error message received was "don't have access to this page".
I found a similar problem here but there is no solution provided. https://social.technet.microsoft.com/Forums/lync/en-US/5d63ec32-94f0-4fba-8ece-8627a04dc24d/access-denied-when-attaching-file-to-item-with-broken-inheritance?forum=sharepointgeneralprevious
Any tips are appreciated.
