while I was listing products on ultimate seo contribution, I realize that the link for the following pages doesn't work.
Instead of searching for the bug I search on internet and find the solution quickly.

Example links:

.html?page=2&sort=2a ----> replace to that, in link it was up to html. ?page=2&sort=2a and similar things on the link were not working.
index.php?manufacturers_id=14&sort=2a&page=2

For those who have the same problem as me: ;

In seo.class.php, (at lines 1060 and 1061)

Find This Lines:

header("HTTP/1.0 301 Moved Permanently"); //let the SE's know to not use this link
header("Location: $link"); //redirect to the real page

And Replace With:

// header("HTTP/1.0 301 Moved Permanently"); //let the SE's know to not use this link
// header("Location: $link"); //redirect to the real page

That's All (No file).
