Note: Please keep in mind that the detailed logs message is taken from the Helpdesk plugin but the error, in general, could appear to any of the RedmineUP plugins.
To solve this problem, you need to increase the size of the field which stores Redmine setting values. So, it is necessary to open the DB console and run the following commands.
- for Mysql:
ALTER TABLE settings MODIFY COLUMN value LONGTEXT;
- for Postgresql:
ALTER TABLE settings ALTER COLUMN value TYPE text;
