Today, I upgraded this website backend (Yes, I’m still using Joomla). After the upgrade, I got the following error
Fatal error: Call to a member function getInt() on a non-object in components/com_postinstall/models/messages.php on line 37
After reading lots and lots that didn’t apply, I found this: http://docs.joomla.org/J3.2:Table_xxx_postinstall_cpanels_does_not_exist
Here’s a summary:
