Hi,
I'm using Sailent v1.1.3 with Joomla 3.6 and of course Gantry 5.
In the back end templates I've a warning as "You are currently running PHP 5.4.45 which will soon no longer be supported by Gantry. Please upgrade as soon as possible. More Details. Theme: Salient (v1.1.3 / rt_salient)"
I might update PHP in my web server but I've a doubt about the old sites hosted on the same server they are in Joomla 1.5 and joomla 2.5 and I fear that they don't work with a new PHP 5.6.
Discuss this with your hosting company. There are usually options to alter PHP version by domain, or to downgrade php version in a site specific php.ini or htaccess file. As of Gantry 5.5 we will no longer support php 5.4.x.
Regards, Mark.
