Bug in admin area

[TopScript]

When i try to filter my products, i get this error:
"The following error was encountered:

* The request or reply is too large.

If you are making a POST or PUT request, then your request body (the thing you are trying to upload) is too large. If you are making a GET request, then the reply body (what you are trying to download) is too large. These limits have been established by the Internet Service Provider who operates this cache. Please contact them directly if you feel this is an error. "

I use Prestashop Version 1.1.0.5

Any help i will appreciate.
Cheers and thanks in advance

I have the exact same problem, and I am using 1.3.1.1. I can filter once, but cannot filter again. Does anyone know what is happening here? How can I solve this problem?

Any help will be greatly appreciated. Thanks!
