Chrome on Mac give me some issues with certain sites (oursurfing.com)

I use bet365 in Chrome all the time, and never had an issue. When logging in, you'd get a pop up that would show you logged in, the amount you have in your account, etc.

There would also be a section where you have your open bets, and you can see your history there as well.

The past week, when I log in to the bet365 site, I would get the pop up in the beginning, with no amount shown.

When I click to see Soccer matches for example, I would get an error message.

I tried resetting my browser, clearing browsing data, and even used Malwarebytes to see if there is any malware.

I did see that when I clicked the home button, it took me to an oursurfing.com page, rather than my original home page.

I have gone ahead and removed that from the settings, but I am thinking maybe that has something to do with this, as when in incognito mode, it works normally.

And assistance would be gladly appreciated!
