Hello I have the Hakuen Studio Window Skin plugin but for some reason it doesn't register on my game and this shows up. I am new to MZ so I'm still trying to figure things out.
First off, see if you are using the EliMZ Book.js somewhere above all other Eli plugins on your plugin manager. You need this.
Now, it seems to me that it is a plugin parameter issue. Meaning, go into the plugin parameter and see if everything is properly configured. A screenshot will also be nice.
Thank you for replying I think my problem is that I tried moving my rpgmaker MV game onto MZ and it didn't like the coding+mv plugins. I started from scratch on MZ and now it works fine. I was tweaking the Vizustella core engine window parameter but it didn't like it either so I'll just go find a menu plugin instead.
