I cannot access that link. By the way AMPPS is for development purpose
only, so its only for local network. If you want to use the same for
production server try our product Webuzo. http://www.webuzo.com
should work on Windows 7. Try Restoring the default configuration of
Apache from AMPPS Control Center (AMPPS Control Center -> Apache Tab
-> Restore Default Configuration).
Also what are you trying to
do exactly? It would be helpful if you gave us some more details.
Please open a ticket for quick support.
