Hello,
I can see a lot of plugins on your site, here is a list of required – https://www.8theme.com/documentation/xstore/plugins/included-plugins/ Read descriptions of all other plugins and disable plugins that are obligatory for your site functionality. Even some recommended plugins can be disabled because every activated plugin slows down the site a bit. Activated should be plugins that you really use only.
WPBakery Page Builder and Elementor – both page editors, you need to select 1 of them, and disable another plugin. You installed demo content that was created by WPBakery, so just disable the Elementor.
1) Please check the Wishlist page now.
