Hello, @Linda,
I have just logged in to your site and found that you are using the Child Theme on your site, Have you Customized anything in Child Theme?
Also, I can see you are using third-party plugins as well, so that might be the third-party plugin confliction issue.
So can you please check once with activating the Parent-Theme and deactivating all the third-party plugins of your site, and check back your site after removing the cache, Hope this will resolve your issue, and if not then please provide me the admin access and also the permission to debug your site which includes deactivating all the third-party plugins and on-site customization as well.
Regards 8Theme Team.
