Hi,

When trying to edit a new product listing in menu, there's a strange layout in the backend. See this screenshot.
I'm using ISIS standard admin Joomla template. It doesn't matter if I choose DIV, table or List. It all looks the same.

Hi,

Please make sure that your "Back-end CSS File" is set to "default". Save the configuration, then reload your backend pages.
