Dear TomQv,
Unfortunately annasta Filters isn’t currently active on the page that your link is leading to, and without it being present on the page it is rather hard to search for the fix.
Furthermore, I would like to stress the fact that by no means this is any kind of “bug” on the part of our plugin. There are ways to attach events (for Quick View and/or other elements) so that they would support AJAX, and the fact that your theme doesn’t do that has nothing to do with us.
Any help with such issues is offered by us exclusively out of courtesy and wish to provide our users with better support. You are obviously always free to contact your theme authors and/or search for a filtering plugin that would provide specialized support for your theme!
