Gan, kenapa yah ane kan udh instal mysql essential terus udh instal xampp. pas klik start pada Apache bisa terus pada MySQL ngk bisa muncul pesan eror :
Problem detected!
Port 3306 in use by ""C:\Program Files (x86)\MySQL\MySQL Server 5.1\bin\mysqld" --defaults-file="C:\\Program Files (x86)\\MySQL\\MySQL Server 5.1\\my.ini" MySQL"!
MySQL WILL NOT start without the configured ports free!
You need to uninstall/disable/reconfigure the blocking application
or reconfigure MySQL and the Control Panel to listen on a different port
