I have installed Joomla on my win 7 PC. I installed XAMPP first (to emulate Apache, MySQL, etc.) on my PC. Getting things to work was a nightmare; see my prior questions on this.
I ran Joomla & it worked; both the front end & the admin site.
Since then I have had to reboot my PC. Now nothing works. The Joomla database is missing from MySQL, phpmyadmin has the pink message at the bottom, etc. See attached.
How do I get back to where I was? Or do I have to re-install Joomla all over, etc.
