HI,
I JUST INSTALLED THE XAMPP AND ACTIVATED THE CONTROL PANEL.
THE MYSQL MODULE WAS ACTIVATED SUCCEFULLY BUT THE APACHE DIDNT
IT SAYS:
Error: Apache shutdown unexpectedly.
22:56:11 [Apache] This may be due to a blocked port, missing dependencies,
22:56:11 [Apache] improper privileges, a crash, or a shutdown by another method.
22:56:11 [Apache] Press the Logs button to view error logs and check
22:56:11 [Apache] the Windows Event Viewer for more clues
22:56:11 [Apache] If you need more help, copy and post this
