Red line

Try Blocking Element Lumpy.

My red line is gone but there is a ghostly line that blocks out the forum, it doesn't really bother me but still a bit annoying.

There's be somewhere on that line that you can click and block element on AB+

Mine too. I have to remember not to try to add anything within that line.

I've just got rid of the red line advert & the harrod horti adverts on the iPad!! Click on new posts & at the bottom under the posts there's a little search bar that says gyov4 touch it & change it to gyov4dev. Hope it works for you?!
Edit to add I think this would work on the pc too?

Jungle Jane's advice worked for me, once I'd clicked on gyov4dev the ghost white line was gone and everything was working again
