First it says it can't start the MySQL... (in XAMPP Control panel).
Second the phpmyadmin doesn't open, it says:
#2003 - The server is not responding
And third, i can't open the http://localhost anymore, first it ask me for my username and password, (and i enter it correct!!) And after that it says it can't find the page... I reinstall XAMPP 5 TIMES, and it didn't help!!! So first it was the port problem, and now its the 3 Unknow problems... -_- Can someone tell me what to do?! I didnt found something useful in the FAQ! Please someone can help?
