Error: MySQL shutdown unexpectedly

Postby marzia » 12. February 2021 07:55

I am a beginner in using Wordpress on localhost. Please can you help me and please explain in an easy way (step by step) ;)
When I start the MySQL module in the Xampp control panel today (while it was perfectly working in the past 2 weeks) I get this error:

08:21:48 [mysql] Error: MySQL shutdown unexpectedly.
08:21:48 [mysql] This may be due to a blocked port, missing dependencies,
08:21:48 [mysql] improper privileges, a crash, or a shutdown by another method.
08:21:48 [mysql] Press the Logs button to view error logs and check
08:21:48 [mysql] the Windows Event Viewer for more clues
08:21:48 [mysql] If you need more help, copy and post this
08:21:48 [mysql] entire log window on the forums

When pressing the Logs button I get following info:

Error: MySQL shutdown unexpectedly + uninstall Xampp

I tried to fix the MySQL shutdown unexpectedly error with help of previous answers from the forum but I did not succeed.
I uninstalled Xampp and reinstalled it allowing the access to Windows Defender Firewall blocks on private and public networks. Now MySQL in Xampp is working again (!!) but I lost all my database and websites I have created on localhost!
How can I avoid to loose all my work next time when I have to uninstall/reinstall Xampp??
