I am tried to upgrade my gallery from 3.2.1 to 4.0.1 and it failed
Joomla 2.5.7
I did the installation in the administration->extension install package

The website encountered an error while retrieving .../administrator/index.php?option=com_phocagallery. It may be down for maintenance or configured incorrectly.
Error code: 500

each time I click on the control panel that shows up.

Nevermind, I found the problem.

I upgraded to 3.2.6 with no problem.

4.0.1 is not for joomla 2.5.7
