I also have this problem. And I find it occurs when you edit your listing. If you remove some text you will then find a large space. After much playing around – I found a work around. It is a “MAJOR PIA” and should not be happening on a site like this (but it is).

Here is what I [URL removed] Go to your Detailed Item description and click on Source. You will now see the HTML coding for your description. You will also see row after row of this [URL removed] &.n.b.s.p;

This area will not allow me to use code – so I have put periods in the offending code. Remove them and you will see the correct code.

This is what is creating your large blank spaces. Delete this code. And then click on Source again. You will be back in Standard listing and your blank areas are gone.

If when you list something and use the Duplicate button and that listing has had any editing done to it your new ad will then have all those blank areas.

Here is one of my listings with a lot of blank [URL removed]
[URL removed]

Here is one I just recently [URL removed] [URL removed]

Instead of using the duplicate button to sell similar items – I now have a Sample Ad which I check regularly to see that it does not have the blanks- (if you leave the price out is does not show up in your booth).

I am not that proficient with writing code, but I find this works for me and in my opinion is something that should have been addressed some time ago by the powers that be. All those blank areas showing up on mobile devices would definitely be a turn off to any prospective buyer.

Sorry for being so “long winded” with this answer

Hi, me too. I can’t add new listing, for example, when I try to add images, the add button not active.
