Hi there, when enabling Ajax filters (v 3.8 supported) on our nopCommerce 3.8 site, we receive the following error in the console:

jquery-1.10.2.min.js:4
Uncaught Error: Syntax error, unrecognized expression: .master-wrapper-page ,

We'll try to add a little more detail, but if you could let us know if you've seen this issue before that'd be great - thanks!
