title: SharePoint Web Part Access Denied error
body: <p>I have a list in my sharepoint site.The users who have contribute access is able to add items on the list.But recently some users who have contribute access was not able to add new item.The normal work around we do is we will add them to the owners group and ask them to login .Then we ask them to logout and remove them from the owners group and issue will be resolved.But the proper way shouldn't be like that.Please give the proper way to solve this issue.</p>
