I do not know if I can publish the solution, if the administrators consider it inoperative please delete it.In your database, "ost_ticket" table, edit the "source" field.Under the "Length/Values" column select "ENUM/SET" option. Add the values you need.In the "Default" column select "custom" and enter the name of the ticket's origin. (Web, for example)Edit the include/staff/ticket-open.inc.php file at the end of line 133 change the value to 'Web';Edit the include/staff/ ticket-edit.inc.php file at the end of line 76 change the value to 'Web';Edit the include/class.ticket.php file in the array of line 143 add the same values you added to the database.This was enough in my caseRegards!
