Computer Help and Support

This can be caused by ...

1) the scripts on the website being poorly written (e.g. not your problem), or
2) your computer being slow to the point of not being able to work well (e.g. Malware or failing hardware ... very much your problem), or
3) your Internet connection being slow to the point of not working (your ISP's problem or your local network problem or your computer problem).

The browser (what is putting up that message) can't really tell which of the three situations is causing the problems, hence the somewhat less-than-stellar warning message.

So test with other sites (and other browsers), maybe reboot, and see if the problem persists. Most of the time it will vanish, but if you're unlucky there might be something for you to fix.
