Error: MySQL shutdown unexpectedly

Postby kezf » 31. March 2016 01:25

Hi, can anybody help me on this?

That's what the XAMPP Crontrol Panel's Console is displaying when I attempt to start MySQL :

20:15:14 [mysql] Attempting to start MySQL app...
20:15:15 [mysql] Status change detected: running
20:15:17 [mysql] Status change detected: stopped
20:15:17 [mysql] Error: MySQL shutdown unexpectedly.
20:15:17 [mysql] This may be due to a blocked port, missing dependencies,
20:15:17 [mysql] improper privileges, a crash, or a shutdown by another method.
20:15:17 [mysql] Press the Logs button to view error logs and check
20:15:17 [mysql] the Windows Event Viewer for more clues
20:15:17 [mysql] If you need more help, copy and post this
20:15:17 [mysql] entire log window on the forums

...and that's what the log window is displaying :
