I Instaled Opigno 2.9 with composer. After the installation, I went to the update.php to update the packages. After all, I can't access my OPIGNO. The is an error UNRESOLVED DEPENDENCY - GGROUP Missing in more than 15 modules/services. I looked for a solution because I tried three times and I saw just one solution: No Upgrade Group Module/Pack.... But I think it's not a solution because I think there will be a time when I will need to upgrade it.
Please, somebody could help me?
