I have created a custom permission level group called custom contribute. The group permission seems to work fine and smoothly one day. The next day that it seems that users of the group can access the site but they cannot do anything else on the site without receiving the tell us why you need access message.
The users in the group are accessing SharePoint from all over the world. Is there something that I can check within the settings to see why they have access one day and the next they don't? Or is SharePoint setup this way?
I have full control of the site and nothing changes from day to day. Any help or suggestions on this would be greatly appreciated.
