This page cannot be found - link from WebLink

How do I fix this issue? When I click the Web Link button (1), a window appears saying "This page can't be found" (2) with my homepage text. I'm interested in one of two solutions:
1. Either the link or website will be displayed correctly,
2. Or I'll make this option unavailable, and the Web Link button will disappear.

For some reason, I need a quick response, for which I thank you in advance.
