I am a Yahoo Small Business Subscriber. When I go to the Web Hosting Control Panel and select the "Create & Update " tab then the "Site Solution" button, it says "Loading", then takes me back to the "Home" tab of Control Panel. There is no message about a pop-up trying to load.

How must my bowser be configured?

How must my firewall be configured (Ihave tried the Windows Firewall and the Trend Micro Firewall)?

You can try a different browser to see if that might be the problem. However you can turn off popup blocking through the "tools" menu in IE 6 and through "tools >> options.. >> content tab" in Firefox. Then try it again.

If you turn off your popup blocker and it still doesn't work, then you can first try skipping the router/firewall you have in place by directly connecting your computer to the modem. See if it works then. If it works then, you know it is a setting on your router.

If you haven't already configured it with a bunch of settings, simply reboot the router and see if that helps. Lastly you can go in and check to make sure all your ports that you need are properly configured and make sense. Get rid of any entries that you no longer use and are blocking ports. Not only can this help with the problem but it will make it more secure by eliminating possible holes in your security from programs that you don't use not using the ports anymore.

Hope this helps and good luck with the effort.
