Check your PHP version - I've found that Gantry 4 doesn't play nice with 7.1 or 7.2.
7.0 seems to be ok, depending on your setup.
Hope that helps. - Good things come to those who wait - but it's only what's left over from those who don't

- Well, Gantry 4 works fine. It's running PHP 7.1.25 at the moment. My issue is that the site *only* lets me use Gantry, when I need it to allow me to use other templates. It's perplexing... I definitely don't want to downgrade PHP, though. I'd rather patch / hack Gantry4, if needed (although I'm unsure what the issue is here).

Try going into Extensions / Manage / Manage and search for Gantry and just make sure everything is running the same version.
I know with some of my Gantry updates I've had to uninstall older versions floating around and then manually re-install Gantry 4 (downloaded from gantry.org/ ) - Good things come to those who wait - but it's only what's left over from those who don't

NEW INFO: I've made a dev copy of the site in question and have been testing to solve this. I *think* in fact I've stated the problem wrong! I think the site itself has an issue, and Gantry happens to fix it somehow, which is why ONLY Gantry templates work on the site. The problem, I now think, is that my **Joomla hidden menu items** do not work unless they are on Gantry templates. Any hiden menu item I create and assign Protostar or whatever does *not* work -- throws the Error: Call to a member function get() on null: Call to a member function get() on null. Still researching, but if anyone has thoughts, I'd appreciate them.

It's possible that you have an extension that is not compatible with PHP 7 yet.
Try:
switching back to PHP 5.6
upgrading all third party extensions to the latest versions
See docs.google.com/spreadsheets/d/1HJj02l3B...t?pref=2&pli=1#gid=0 for which extensions are compatible with PHP 7.0. - Good things come to those who wait - but it's only what's left over from those who don't

Thanks. I did try PHP5.6... That actually helped a bit, as the error reporting was more robust. Instead of the non-identifyable error shown below, it now included info as to the source:
Notice: Undefined index: in ...public_html/libraries/gantry/gantry.php on line 126
Notice: Trying to get property of non-object in .../public_html/libraries/gantry/gantry.php on line 207
Fatal error: Call to a member function get() on null in .../public_html/libraries/gantry/gantry.php on line 267
There have been other threads (all unsolved,as far as I could tell, related to this. One was:
rockettheme.com/forum/gantry-for-joomla/...-member-function-get
Anyway, the weird thing is that this was happening even if no pages were assigned to the Gantry templates I have installed. (The site uses two, and I'd installed a third for testing.) I tried assigning ALL pages to Protostar & was seeing the Gantry errors, above, on hidden-menu items only.
Then I tried completely disabling all Gantry extensions (and templates) and still got those Gantry errors (which is weird because, if Gantry is totally disabled, why is it being called?).
FINALLY... I *uninstalled* ALL Gantry extensions and templates... and bam, Protostar started working again.
The issue isn't solved, unfortunately, because I still can't use Gantry AND a non-Gantry template along with it (at least on this Gantry4 site, on hidden-meun items). I also reinstalled all core Joomla files, just in case something was corrupt. Didn't help. IDK... I think I'm just gonna tell the client that, for this project, we need to get rid of Gantry altogether. It's Gantry4, anyway, so not a giant deal. I'd still love to know what's going on, though. Super frustrating! - ______________________

could you be more specific about the issues you have with Gantry 4 on PHP 7.1 and 7.2?
We're not aware of any issues in our latest versions, apart from a few notices which we're going to address soon. - Kat05 / QA Lead & Support / Germany

Certainly.
In particular this website.
crcore.org.au/ gets the following error message on anything above 7.0 (Sorry I can't keep showing the error message as it's a live site)
Warning: session_start(): Failed to read session data: user (path: /opt/alt/php72/var/lib/php/session) in /home/wcwcdohj/public_html/libraries/joomla/session/handler/native.php on line 260
Error: Failed to start application: Failed to start the session
I will have to hunt around for some more, but that's the one I was thinking of (most of our client's we've upgraded to Gantry 5 - not too many 4's floating around) - Good things come to those who wait - but it's only what's left over from those who don't

Hi again,
I googled a bit and any results I found where people came across that same error, it was suggested that it's a misconfiguration of PHP on the server. You should compare between the working PHP 7.0 and the broken PHP 7.2, or just check back with your host about the differences.
