When I open XAMPP and click start MySQL button and it gives me an error. I had started it just before, but now it isn't working.
It given error below in xammp

What is the cause of these errors and how can I rectify them?
Open data folder and delete all ib_logfile* (ib_logfile0, ib_logfile1). Then restart xamp, so it solved for me.
