Hello Ivo
I wanted to upgrade my Joomla version from 3.8.6 to 3.8.13 or 3.9.0
First off I took a backup and then started to do extension updates.
I updated Gantry and now the site displays a blank page or in chrome gives a HTTP error 500
Can you help please? Do i need to roll back or upgrade the Joomla in line with the Ganttry update?
