Missing navigation

[kamikaze cow]

As you can see, there are two navigation links, the first and the last page but not the other pages in between:
http://www.salsafuerte.hu/gallery/
http://www.salsafuerte.hu/tmp/coppermine.jpg
The images are uploaded by the teachers so I don't know what happened and when it happened.

Thank you for any help.

<!--Coppermine Photo Gallery 1.4.10 (stable)-->
You need to upgrade to at least 1.4.27
You should consider upgrading to 1.5.8 as support for 1.4.x will run out very soon.

This is probably an issue with your custom theme. Attach your theme.php as theme.php.txt to your next post.

I will upgrade soon (I am afraid of upgrades because of modifications I have made and I don't remember:).)

I made this template more than three years ago so it is not too elegant, sorry:)
Thank you for your help.

It looks like the classic theme is affected as well
