Hi all,
with Joomla 3.5.0 being released today, Joomla itself is now also compatible with PHP 7.
You will have to update Gantry 4 to 4.1.30 to be fully compatible with that version of PHP as well as several of our extensions, please take a look at the
Product Updates
page, PHP 7 fixes are mentioned there.
Depending on which Gantry 4 template you are using, you may also get a warning displayed, which is:
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Color has a deprecated constructor in /Applications/MAMP/htdocs/jo_extensions_demo/templates/rt_extensions/features/color.php on line 11
(Please note that the line number may vary depending on your template)
To remove this warning, you can edit the following file
../templates/rt_TEMPLATENAME/features/color.php.
Please find the following line:and change that to:function __construct($hex){
We'll be releasing these template updates over time and make sure to get Joomla 3.5 RocketLaunchers ready as well, but in the meantime, you can apply the above change manually.
Thanks 
PS: Using Gantry 5? Please find some info
