Hi chezzy, do you have a VIEW tab at top of your search enging page ? Click on that & try reducing down a size or two.

Strangely the ad that is blocking you doesn't appear in your photo.

Lets hope we're not all in for this new glitch !! Us paying [meaning sellers] outside advertisers to block us searching ... what a joke !

I actually did  a search on my items before I logged on, had cleared all history & cookies last night, so fresh start this morning.  One item hoho, a BOOK, didn't even appear in my View Sellers Other Items. so just one more glitch among the hundreds or another black hole.

Good luck with getting your screen back to normal
