XSS worm on my InfinityFree site?

Thank you. The problem is that the issue is intermittent. It doesn’t fail every time so I can’t be sure that no problem means the problem is fixed. But it has failed enough times that it isn’t just a one time fluke either. When it does fail it’s on the first visit but not every first visit fails. I just opened Edge which I never use and visited my site for the first time ever using Edge. That was a first visit and it loaded just fine even with the cloudflare proxy still active. When I say first visit I mean waiting several hours not visiting my site and coming back to it in a new private window.
