About the mobile view…as I see you have a problem with the responsivity.
That easily can be a problem with some plugins you have installed.
To check if this is the case, try to temporary disable every plugin that you have activated, and re-enable it one by one until the problem happens again so you can exactly found the plugin what causes the issue.
If this solution didn’t work, send us your Admin user/pass in private reply (or make another temporary Admin user for us ), so we can take a closer look.
Actually, this line showing the “home” inscription is a Breadcrumb.
If you want to remove it, on the front page, edit your front page, scroll to the bottom of the page, find the “Agama Page Options” meta-box, open the “Breadcrumb” tab, and disable the breadcrumb.
We checked your site and founded that you have
Disabled responsive content elements on WPBakery Page Builder Settings. This caused the whole issue with the page responsivity.
so we unchecked that option and now seems to everything works properly.
