MySQL suddenly stopped working

Postby funkpunk » 25. January 2016 12:32

Hi all. I've been using XAMPP for a few months now creating a local site using Joomla and all had been going well until this morning. For no reason, ie no crashes, updates etc, MySQL has stopped working. It tries to load then bombs out with the following error message. Any help would be great as the site was nearly finished!
