bbPress.org

1. I see you’re using 1.0.1. I would recommend upgrading to the latest to see if that happens to fix it.

2. I added a tag to a topic, and I do not have the [X] to remove my own tag. Why can’t I delete my own tag?

There is also some additional functionality where it shows ‘tree’ by ‘chrishajer’ – that’s not there by default, so how is that being added?

This error does not occur by default in bbPress, so there is something specific about your installation. If it’s not the template, maybe it’s a plugin or something else you added.
