Search, blocklayered and grid view don't work on category page

Search, blocklayered and grid view don't work on category page.

Strangely enough Search works on the homepage.

 

It seems that when I try to use any of them there is no POST action, but there is for the search on the homepage.

 

Any ideas what is wrong?

Sounds like a javascript issue, can you share the site's url?

Here is the link:

There are 2 JS errors on the page ... but they don't seem connected

The layered navigation seems to work for me, as well as the search

Argh ... this is infuriating ... just before asking for help I deactivated friendly URL -> reindex -> activated friendly URL back ...
and it seems that for some reason on my machine it still doesn't work ...

but on other machines it started to work ...

thanks Nemo1 for the help ... it seems that I have to burn my current linux distro and reinstall/search for something else :|

Tell me please, can the display of these objects to work properly if I started to use proxies lately? That is, can such a reaction be in sub ip roughly?
