I have a weird problem with SharePoint 2010 site permission which just started happening the other day and I can't find a solution.
If I manually grant/add a user access to a site through site actions > site permissions. The user can't access the site even though it says they have access.
the only way for the user to get permission is to go to the site and request access. I can't just add the user in the site permissions tab.
how can I fix this? I have a feeling someone with full control changed a setting or something.
It's likely that the user needs to be a member of a group that has access to view underlying resources, like the site collection style library and masterpage gallery, or images/webparts displayed on the home page.
Simply granting them access to the current site may not grant them the access they need to view those underlying resources.
