I just downloaded the Ampps updater because I was running Ampps 1.9 and the new version is 2.2. When I start Ampps, MySQL has started OK. I can click the Start button to start Apache, but nothing happens. I can't access Ampps Home or Ampps Admin anymore either.
I tried running httpd.exe from the command line in Windows 7, and there are a number of errors with my httpd.conf file - mod_authn_default.so not found, mod_authz_default.so not found and so on.
I've probably done something silly - my experience setting up Ampps / apache is very limited, but I would really value any help you can give. I have opened a ticket
