Pagination problem in Back Office

[Mr.E.]

hello,

When I go to the back office and I select a category, i can view only the first page of products.
If i click on the small arrow to go to the next page I get an 503 error page Saying:

Error 503 Service Unavailable
Service Unavailable

[spam-filter] Meditation:
XID: 536316535

(with all the categories listed) instead of being going to the next page with the products from that category.

I have this problem in my previous installation(Version 1.1.0.5 - 1.045s ), and now I uploaded a 1.2.5 version to another directory on the server and installed it as an upgrade using the same databse settings.

Everything the should works seems to work except that pagination problem.


Can somebody help please? Any idea, how to solve it?
I also tried some file mentioned in this post but didn't help: http://www.prestashop.com/forums/viewthread/36339/configuring___using_prestashop/_solved__back_office_pagination_problem/


Thanks in advance.
