Did you mean the link not worked? I'm managing to download it here just fine.
Did you try this one, right?
Can you show to me a screenshot of your plugin manager?
I don't see Eli Book on your plugin manager. And I also see that you didn't understand one of my answers.
On your plugin list, I can see only this plugins of mine, and still, it is the MZ version, not MV:
So please, install the MV version of my plugin on your project, and send me a screenshot of them again so I can check.
All my plugins need the Eli Book to work properly.
