Last night MySQL Service on my XAMPP local server was running fine. Today... it starts for 10 seconds and then give me following error:

Apparently, there doesn't seem to be any error. I have an older version of XAMPP that is workin' fine, which means there is no Port 3306 issue.

I have tried couple of suggested solutions on other platforms, e.g. deleting ib_logfile0, ib_logfile1, and ibdata1 files and adding

innodb_force_recovery = 4

to configuration file, that didn't work for me.

What could be the issue here?

first suspect .. the usual - "windows happened" - Wednesday = patchday - there is potential risk that one of the updates "f**ked" things up - and in most cases a simple reboot should do it.

But if you tried with a second mysql server ... make sure that the port is free when you try to start this one the next time.
