I’m afraid adding that code to the .htaccess didn’t work. Also, as I mentioned previously, I would prefer ajax work rather than pagination. I’m afraid moving the site out of the subfolder isn’t an option either. I really hope you can help figure this out! Thanks very much!
If we can make pagination work on your site, AJAX would work automatically since it just reads the pagination content via JS. If you post FTP information for the site, I can see if we can figure what’s happening. This is mostly configuration issue than a theme one. If you switch to the default theme, you will see the same pagination broken on your site.
