Error Upgrade ojs from 2.3.7 to 2.4.8

Hi I have this error upgrading ojs from 2.3.7 to 2.4.8
(mysqli): SELECT setting_name, setting_value, setting_type FROM plugin_settings WHERE plugin_name = ‘coinsplugin’ AND journal_id = 0


(mysqli): SELECT setting_name, setting_value, setting_type FROM plugin_settings WHERE plugin_name = ‘acronplugin’ AND journal_id = 0


(mysqli): SELECT COUNT(*) FROM plugin_settings WHERE plugin_name = ‘acronplugin’ AND setting_name = ‘enabled’ AND journal_id = 0


(mysqli): INSERT INTO plugin_settings
(plugin_name, journal_id, setting_name, setting_value, setting_type)
VALUES
(‘acronplugin’, 0, ‘enabled’, 0, ‘bool’)

ojs2 has produced an error

Any idea ?

Hola Enrique, podrías detallar el proceso completo que has seguido para actualizar? gracias.

Hi

I download the versión 2.4.8 and copy files and public directory to this. In config.inc.php scheduledtask is off and installed is off and debug of database is on. The database is a dump to the original. And then run php tools/upgrade.php upgrade.

Thnks

I have the same problem, managed to solve?
