Thread:Project:Support desk/Database error after updating to 1.20.4/reply (3)

You could add the column, but you have no guarantee that this would solve the base of this problem. It would be better to know, why it is missing. In some cases the installer does not only create empty columns, but also fills them with content (with content, which you do not know). Maybe some other columns are missing as well. So just creating this missing column is not enough.
