These kind of tricky interaction issues are going to crop up every now and then as Discourse keep changing their composer. At the moment you’re the only person who we know of that uses this plugin. We can’t support it indefinitely for free for one user. If you want long term support for it we’ll need to discuss a support contract.

OK, let me know the next steps.
