When I click "next" I get sent back to the index.php page

Snarf? · May 3, 2008

If a category has more than 20 items and I click next to go to the next page of products I get sent back to index.php. I've searched the forums for a solution to this problem but still can't figure out what's going on. I have chemo's seo urls contribution installed but none of the fixes for described in the forums work. It's very strange. You can see for yourself here: http://bakerjosh1979.startlogic.com/store/...ds-c-21_42.html

Here is my seo.class.php file :

Any help will be greatly appreciated.

I believe if you find the support thread for the particular SEO contribution you are using you'll find this problem has been addressed.

At least that's what one very admired, competent poster (who posts in that thread regularly) here told someone who posted in this forum with your exact same problem.

Thanks. I'll post in that forum as well. I'm familiar with the solution that was provided there but since my version of seo.class.php is different from theirs it doesn't apply.

When I click "next" I get sent back to the index.php page
