This may be happening elsewhere, but so far I've noticed two particular issues.

1. https://subeta.net/explore/directory_building.php?page=278&order=itemid&type=0

On the item directory pages, where the page numbers are all 3 digits, the page numbers extend beyond the edge of the page and I can't see or click the [last] button.

2. https://subeta.net/explore/vesnali/bouquets.php

On the bouquet page the flowers jump all over the place based on how wide my browser is, sometimes overlapping each other.

random browser widths

Hmm have you tried scrolling from left to right on your screen, (if you use a tablet try pulling the page to the side) to get to the buttons?

Still an issue that needs to be looked into but just offering some help (if that helps) till then.

huh...that's weird. I was going to say I'm on a PC and there isn't a left/right scroll bar. But then I paged all way to the bottom, and a scroll bar showed up, which means its attached to the page and not the browser.

I can access the [first] button, and on the first page the [last] button shows up because the page numbers are narrower. If I use the scroll bar attached to the page I need to scroll to the bottom, move the bar over to the right, then scroll back to the top to hit the [last] button. LOL either option is annoying!
