If you getting following error
Could not execute menu item (internal error) [Exception] Could not perform service action: The service has not been started
please make sure none of following services is running on your system.
IIS, Skype, Zone Alarm, NOD32, Eset, Internet Optimizer, Google Accelerator, any other database server, any other webserver?
If you using any of the above application close it and select “restart all services” from WAMP menu.
under Apache open the httpd.conf and change the lines
Save the file and select “restart all services”, it is done
Thats all .. Cheers
A strange thing is that when i was getting this problem i closed the Skype and restarted all services and wamp was up and running. But again i started the skype and it give me no problem again … :D
