Trilbymedia/grav-plugin-flex-objects - NOT working

Hello,

i have a new Grav Website running with the Learn2 and Learn2Git Themes. I tried to install https://github.com/trilbymedia/grav-plugin-flex-objects/ through the Admin frontend and got an error saying, that the url is not right/valid.

I installed the plugin manually through Admin -> Tools -> direct installation. Uploaded the .zip file and the plugin was added to my list.

When i click on “Flex Objects”

i get this error:

Can anyone help me?

Please provide some information about which version of Grav you use?
Flex-objects can’t work in Grav < 1.7.

Thank you very much… I installed Grav 2 weeks ago and i thought it would be the latest version, but it is Version 1.6.21…
