Hi, can you press F8 and switch to the console tab in the window that opens up to show me the full error trace?
It sounds like you have typed in a preset into one of your note tags that does not exist. Could you double check that your preset in your notetag matches exactly the id you set in the plugin parameters?

Hi, I am glad you got it to work, do you mind sharing how you fixed the problem from before so I can look into what happened?
For your new problem, if you are using an image, the plugin assumes that you want the map name window to display to display the image (with the idea that people could make their map name blank and then use fancier text on an image that displays). If you don't want this behavior you can edit the .js file, specifically in the function "Window_MapName.prototype.open" in the first line, change this:
if((!this._settings || !this._settings._image) && !$gameMap.displayName()) return;
to this:
if(!$gameMap.displayName()) return;
