EROAN

Bought and installed today in replacement of Advanced Tags & Prefixes.
It took 3 minutes to make it work, I thought I would have to run through conversion steps but no, it works as this.
Thanks very much for developing this plugin, I couldn't have updated the forums to last version without it.
For those who hesitate, don't 😉

Just for those that come after – Makoto fixed the problem quickly. 
Thank you for the help! 🙂

I don't do release tests, but assume yes unless anyone indicates otherwise.

Got it. Yes, that should work as expected.
 
Understood, thanks. I'll look into it for the next update, but otherwise, unless you see something break, you can disregard the "DB errors" the support tool reports. The support tool is known (notorious) for misinterpreting the database schema, writing it one way and then reading it as something different, when it's actually the same. Evidently they changed something about it in 4.1.14, and this was a side effect.

The Support Tool is complaining about the database structure. The support team solved the issue for me, and I am attaching the file to this post. The explanation is as follows:
 
queries.json

I haven't tested. But there's no reason it wouldn't.

This app works in IPS 4.1?
