Unable to sort result list in a search crm 2007

Hello everyone,

I am facing a problem in CRM 2007, Iu2019m going to describe it.

When I try to sort or filter a result list in the webclient, It is done by clicking on the header of the result list, well when i click on it instead of appearing the options ( such as ascending , descending or any value of the selection) there is a error in the web page ( so a sign of error appears in the left bottom corner of the screen)

For instance if i search an account with a * then many possible accounts will appear in the result list, but i can not sort them by clicking on the header of the result list.

Any help?

Thanks in advance.
