I get the same error when I double-click on the file, but that's now how plugins are supposed to be used anyway. It sounds like your version of RPG Maker's JavaScript interpreter doesn't recognize default parameters... but why it wouldn't I can't begin to fathom, as I've never had that problem.

Alright guess it doesn't matter and I'll just try and work around it, I dunno, still can't believe that this is the only plugin that's done that so far with plenty others.
Hey I was wondering if this is an issue, do you think I would have problems with your other plugin - soundtrack manager for RPGMV? Really would prefer not to waste my money but I cannot find these things anywhere else.
Idk how refunds are handled either here but that's not all that important... Really appreciate your support
Soundtrack Manager has no default parameters in its functions, so you likely wouldn't see this particular issue - at least, if in fact I correctly understand what the issue is. For the record, Dualtechs and Actor Icons don't have default variables either. Battle VA Manager does, though.
I could rewrite the plugin to avoid the default parameter issue when I have the time, but it's weird it's happening in the first place. And if you want a refund instead of an alternate version, then... I don't know how itch.io handles it or if it even does, but I can try to look it up.
I'd love an alternate version that would work, that'd be amazing, I didn't know that was an option though, I'd be willing to pay a bit extra too since I'm bothering you so much and you don't even have to do this for me - sorry! Thanks again for being so helpful.
I don't know how we'd go about contacting each other at that point , because sorting this stuff out through comments here is janky but basically I'm okay with anything since there isn't a DM feature in itch it seems(I think)
If I'm right about the problem being default parameters, then it's certainly possible; default parameters are just a shortcut. As for communication, I'm on Discord, same user name as here (don't abuse that fact, please). Or I could just put it as an alternate download; if you've already paid you should still have access. While looking over the Pro plugin, I did notice a little bit of silly redundancy - unrelated to any problems you're having - that I should probably remove in the "main" version anyway.
