Hello,

I have test your site. Some of your theme options not working correctly like the “Product Grid” in the theme options.

As you are using an old version of theme and outdated theme required plugins. Kindly update the theme and plugins as well.

Also after updating the theme you have to deactivate the third party plugins one by one. Because some of your third party plugin conflict with the theme. This will surely fix the issue.

Best Regards.
