Thread:Project:Support desk/ 1.16 1054: Unknown column 'user options' in 'field list' (localhost) (2)/reply

In your database you have a table called "users" and in that table the column"user_options" is missing.

Try running the file maintenance/update.php from the command line. This script can update your database; however, I do not know if it will add this column in your situation.
