I am using Joomla 2.5.6 for my website. When I try to add a new article under content from the top menu, I get the error : "You don't have permission to access/administrator/index.php on this server”
But if I select an existing article's check box, and select 'edit' I can edit the article normally. I can also open a new article using the right menu in the article manager page without any issues.
Does anyone why is this happening and how to fix it?
