tested gain enabling breadcrumbs in your plugin setting then stops the add new plugin search feature working

found the issue was due to not having enough space on the server to download and unpack the update files.

ok resolved now it wasnt ad from sidebar though it was same size, it was setup in placements for some reason the visitor setting wasnt set it their.

i can still see it

see screenshot:

you can see two ads the top one is 300×250 i dont want to see these on mobile they are too big
under it is a smaller banner style ad that it is ok

this is screenshot from a sony xperia phone android

I just found this but a simpler free version would suit me.
