TinyPortal

I have given a membergroup the following additional permissions:

TinyPortal Articles
Submissions are always approved Yes
Can submit HTML articles Yes
Can submit BBC articles No
Can edit own articles Yes

However when a member of that specific membergroup uses the "Write HTML article" option to create an article they get a message saying: "The article was not found" right after they click "Save" on that article.

In the User block of the Admin it shows that there's a new submission (# Articles) but clicking that link leads to the following error:
Unknown column 'art.author_id' in 'field list'

The Admin is able to create articles without running into these issues.
