Our site is getting this error " DB Error: Unknown column ‘u.last_name’ in ‘order clause’ " and we cannot log in anymore.
Seeing the DB throug phpMyAdmin, I realize that there’s no column named ‘last_name’ nor ‘first_name’. This is affecting our website since the names of the authors or users are not displayed.
We are using OJS 3.1 and PHP 5.6.4 and the logs in Plesk aren’t showing any errors with the PHP.
Can anyone help me with this? Thanks in advance.
