I am also getting “There was an error when creating the topic” however the topics are being written to the database fine. This only seems to be happening when a group is set to ‘private’ or ‘hidden’.
When the group setting is changed to ‘public’, all of the posts in the database for that group appear and the error is not shown when making new posts.
If the group is public then the forum posts show up in the Forums Directory, if they are private or hidden they do not – which is expected – however the tags for hidden or private posts show up in the ‘forum topic tags list’ – not to serious though.
