Hello @Wep287,
We recommend that you update the XStore theme and XStore Core plugin to the latest versions. The latest versions are XStore 9.0.4 and XStore Core plugin 5.0.4. You can view the changelog here: https://xstore.8theme.com/update-history/.
We also suggest that you read our theme documentation to update the theme: https://www.8theme.com/documentation/xstore/theme-installation/theme-update/.
I have checked your site and found no issues. The header menu and submenus are working correctly when hovered over, and the search function is also working correctly. On your site, the search function only works for searching by category. To change or set the search result sorting, simply navigate to XStore > Theme Options > Header Builder > Search, where you can turn the result sorting on or off as needed. I have created a video for you to watch for better reference:https://www.veed.io/view/e88f1f5c-f5f6-4554-8f5e-d36e2bc696be?sharingWidget=true&panel=share
Best regards,
