In trying to upgrade from D7 to Backdrop, I wanted to preserve forum.
Noticed there's a Forum module; so I put this in modules folder.
Didn't follow advice about uninstalling Forum from D7, as I figured this would delete all the content.
Now, after "upgrading" to Backdrop, I find the link to Forums leads to page reporting there are no Forum posts. No listing of Forum topics, either.
But, in taxonomy, I can see the Forums vocabulary from before; the terms are there too. So also the content, with links to this appearing in a module that automatically links to a few Forum posts.
Been looking to see if I can restructure the taxonomy, so the terms are switched to a new Forum I've made. But I can't see how to do this.
While trying to make a Forum container, I get this error message:
Argument 3 passed to taxonomy_overview_terms() must be an instance of TaxonomyVocabulary, boolean given, called in /usr/www/users/hkout/backdrop/modules/forum/forum.admin.inc on line 292
Likewise, there's an error in trying to list Forum containers, via Structure [Control forum hierarchy settings.]
