Im using the beautiful J51 Oxgen template. I need for the users to post news in the front page so i created a link for that.

The issue is that when the user clicks on the button under the textarea to post Articles or Images the popup selection screen has no CSS therefor nothing can be selected.

I tried by changing the theme for that particular menu item but it doesnt work, while Oxygen is the default theme overall i get the same result. When i declare another theme as default, then the popup works just fine. Any suggestion how to fix this?
