Hello, @xyz,
1- Please try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins, clear the cache of the browser, and check then. Maybe one of the additional plugins is the reason for the problem.
And if the issue will still persist then please remain all the third-party plugins deactivated on your site and allow permission to debug your site which includes deactivating all the third-party plugins and on-site Customization as well so that I will check and assist you accordingly.
Note: Please take the complete backup of your site first.
2- The blocks working fine there is no issue with hover see the video: https://streamable.com/i1zq9q
3- Probably you did not migrate correctly.
Please contact your hosting provider. As a rule, hosting support helps with this. Site migration is not related to the theme, so we don’t have any detailed suggestions.
4- Actually, there are no settings for the filters but you can set the sidebar as a toggle. All the filters appear in the sidebar and if you set the sidebar layout to off-canvas then a filter button will appear on the shop page and when the user clicks on it the sidebar with filters will appear to see the images: https://postimg.cc/94K34R6f and https://postimg.cc/213rVD12 this is the only available option in the theme.
