I'm opening a new ticket since the old one (#21212) has been closed while the problem is still present.
How to reproduce
Visit https://www.akeebabackup.com/support/akeebatickets.html
You are on the first page. Click on a different page, for example "page 2"
Now it seems that there is no way to return to the page 1. None of the links such as "page 1", "previous" or "start" works. You can't return to the page 1 until the session expire.
