Grav 1.8.0 beta 1 update : Gantry 5 plugin not working

[svatas]

When you update your Grav installation (1.7.47) to 1.8.0 beta 1, Gantry 5 module in Admin panel is not available and error message occures.

In log file you can see:

CRITICAL | Interface "RocketTheme\Toolbox\Event\EventSubscriberInterface" not found

Updating to latest Development version of Gantry5 (397887e) also does not solve this.

I also updated PHP 7.4 to 8.2 same time.

Downgrade to 1.7.47 is working even on PHP 8.2

we'll look into this Gantry issue.

FYI Grav 1.7 does work with PHP 8.2, and even 8.3.. Beyond that (i.e. PHP 8.4+) we get a bit stuck due to incompatible vendor dependencies.. hence the need for Grav 1.8 which uses much more up to date dependencies, and has a minimum PHP requirement of PHP 8.2
