invalid token in BO...

[gmoussa73]

hey people...i have searched through the forum to know what is the solution for this problem but i found no solution..

in the back office when viewing the catalog of products,there are two tabs for 'filter' and 'reset'....when i try to use them it gives me an error page saying...invalid token with no results.......

frustrating as you try to search for a product in particular but you cannot reach it...tha's a serious problem!!!! i am usin v 1.3.3

any recent solution for this around?

thanx

here is the error i got:

This webpage is not available.

The webpage at http://......../store/admin/index.php?tab=AdminCatalog#product might be temporarily down or it may have moved permanently to a new web address.

and when i refresh the page it appears in prestashop BO with this error:

invalid security token
