We have an “Open Source” plan site hosted on
.discourse.group. Recently, a “Tags is invalid” message has been a problem for our users who are trying to post. I cannot quite figure out why this keeps happening, and how to solve it. I am looking for advice with this.
I fear that several new forum members may have been put off from posting by this, and we may never even have noticed. Considering that our forum is still quite new, this is a serious problem.
We have a “Usage” category. The intent is to require all posts in this category to have at least one tag from the
language tag group. It may also have other tags, but at least one tag from the
language group must always be present. This is because this is a support forum for a software library that has (rather divergent) bindings to several programming languages. Users often forget to mention which binding they are using. Their questions cannot be answered without knowing this.
Here’s the configuration for the “Usage” category:

Illustration of the problem:
This is what happens if I try to create a new post. Strangely, if I then remove all tags, the post will go through (even though one tag should be required).
