After updating the XStore theme to 9.6 and then the core, the sticky header stopped working. I restored the working version (9.4), then tried again (just updated the theme and the core) and it’s still not working.
When I revert back, it works fine. Can I get help tracking down what may be causing the issue? I’m using a child theme, and I even deleted any custom code in the functions.php file just to test and it’s still not working. Thanks!
