Problem still exists after clearing, etc.
First, thanks for the reply.
That's what I thought it might be also, so I cleared all caches with the same results. I also downloaded and ran fresh browsers on this and another OS, and tried the same thing on an alien machine. Same results. Not to be redundant, but here's the specific formula to see what I mean:
Navigate to the Home page of dacfeedstore.com
Click the Products menu at the top to display all products
Click the side menu "High-Performance Horses"
Click either 'Next' or 'Last' to the right of breadcrumbs 'Products 1 to 9 of 10'
Error (link tries to go to products_results.... instead of products_results....
Also, any menu selections made from the top 'Products' menu only, are fine. All the submenus, including the one listed above work just fine.
But, if you click at any time on one of the side menus that exceed one screen, the link is wrong.
