SharePoint 2010 - Access denied when trying to edit a page
The other day a few users were complaining that they were unable unable to edit pages on a site that they had Contribute Access to. After many tries at checking everything was published, I found this blog from Harry Chen: http://sharepointconnoisseur.blogspot.com.au/2011/03/access-denied-issue-while-editing.html Turns out, that read access had been removed (unsure how!) from the site collections Master Page & Page Layout gallery. Following Harry's instructions I was able to add the access back to the library and the issue was resolved. Here's how: Go to Site Actions –> Site Settings -> Master pages and page layouts -> “Library” tab from ribbon -> “Library Permissions” button at the top, right -> Add the users or group to permissions here with at least Read access enabled. Now, owner groups will have the permission to edit the pages.
