@leocg No. I don't intend to do those things. That's a bit too much work for what seems like a simple problem and may possibly cause other issues with my computer.

@burnout426 Update: I just tried that option and the problem is not fixed.

@burnout426 Thanks. I'll try the uninstall/reinstall option and see if that fixes things.

@temminckiiii Thanks, but I don't want to do those things. I have them installed for a reason on my computer. All pages loaded just fine with Opera until I got Windows 11.

@temminckiiii Thanks, but that's not the issue. I don't like MS Edge, so I never use it, as much as Windows wants me to. My default browser is set to Opera, so I do have at least that much figured out.

A few weeks ago, I downloaded Windows 11 OS, replacing Windows 10. Since then, some webpages are not loading correctly on Opera. If I use another browser like Chrome, webpages are loading fine. But if I use Opera browser to search a site, or click over to a site from the FB news page, some sites are loading in very basic format. I'm not sure why or what's going on. I'm using the most updated version of Opera. Is anyone else experiencing this problem? I'm not very computer savvy, so I'm not sure what else I can do to fix the issue.
