I tried to install gantry 5 package to my template.
It was successfully installed. However, when i tried to create a module: gantry 5, the moment I click on the "Pick a Particle" button, I will receive the error below:
500 Internal Server Error
Oops, Cache path not defined for compiled file (D:\wamp\www\Requiem/media/gantry5/engines/nucleus/particles/analytics.yaml)!.
which version of Gantry and Joomla/WordPress are you using please? If you're not using the latest versions, please make sure to update, then clean your Gantry cache and try again.
If the issue persits, please add your link and admin details into the secure tab, so that we can take a look.
I think I know the issue: Please make sure that you have default template style in Joomla (starred one) pointing to the same template you're working with.
In Extensions > Template: Mark one Gantry 5 style as default.
PS: Having default layouts for installed languages isn't enough, you also need a fallback style.
I have the latest versions. Even have done the update today and clean cache.
But I have two languages so I don't really know what to do now :/
Please help
I think you're misunderstanding on how styles work in Joomla.
Basically you need to reverse what you did with default styles and language assignments; instead of marking home pages as your defaults, you should have marked domyślny styles as defaults (star, English, Polish).
