I installed Joomla 3 on my localhost. It worked fine in PHP 5.3.8. I had to reinstall my WAMP and now have PHP 5.3.13. Joomla 2.5 works fine, but a Joomla 3 site just gives this message:
Error displaying the error page: Application Instantiation Error
I read here it might have something to do with bad database settings viewtopic.php?f=710&t=760141
but nothing changed in my websites config files. and 2.5 just works fine.
How to get Joomla 3 going on PHP 5.3.13?
