Hello,

I watched your video and I am not sure if it's a template problem. Could you please activate the default Joomla template and do the same thing to test if there's the same error. If yes, then it's probably a hosting issue.

On the other hand, why would you edit an article through the menu item? In my opinion, it's one of the totally useless Joomla features. Why wouldn't you just go to the articles manager and edit your article from there?

Anyway, I tested the same template on our server, and clicking on the Edit button in the menu item (new menu item that I created) settings doesn't reproduce any bug. Actually, the article is open and can be edited.

 

Regards,
Milos
