Search boxes not displaying properly

Hi.

I’m not sure how or if I messed up the search boxes, but they are not displaying properly. I had made quite a few CSS changes, but I tried deleting all the changes made in relation to the WP Adverts plugin and they’re still messed up. Try as I might, I can’t seem to fix them.

None of the input ID’s are displaying at all. When I type in the search fields, the text does not appear despite the cursor moving (I did not change the color of the font). Also, the cursor only appears to cover half the box.

Like I say, I’m not sure what I did, but any help is appreciated.

Thanks.
