Not letting website open plugin links

I have Sucuri on my WP site and I keep getting an error whenever I try to update plugins that say that my URL “refused to connect.” That’s in Microsoft Edge. The updates do seem to be happening, but this error shows up instead of the update log page that normally shows.

The same thing happens when I try to “view details” on any plugin. I like to check periodically to make sure that the plugins I’m using are being updated regularly and are still good with the latest version of wordpress.

In Firefox, the error says “To protect your security, https://www.magnificentu.com (my website) will not allow Firefox to display the page if another site has embedded it. To see this page, open a new window. I’m thinking it’s a setting in Sucuri.That means that in Firefox, I can click on a button and see the oage I need to see. But that does not work in all plugins. It is preventing some of my Plugins to work properl – ThriveLeads in particular. To design an optin, that one needs to open a page of choices and it won’t.

HELP!
