problem solved.
thanks anyway.

thanks for your quick reply, B! i understand i did something that isn’t supported, but i tried to undo it and i didn’t work. Even when i delete the code from the field and disable display on all devices the error is stil there. it’s a pity that such a small mistake screws up the design of a whole theme! If you could give me any tip on how to try and get rid of that error box it would be much appreciated.
The code that i had pasted on the article bottom ad field was something like this
” <script src=’https://cdn.html5maker.com/embed.js?id=e0ab53c6fe3132d38fdc657beaae80fb9b7057281dcd&responsive=1&width=728&height=90&h5mTag=html5maker’></script&gt; ”

thanks!
