Your software
My Mautic version is: 4.1.0
My PHP version is: 7.4 but I can set it up to 8.3
My Database type and version is: 10.6.16-MariaDB-cll-lve-log

Your problem
My problem is: that I can’t do any update or upgrade from the 4.1.0 version.

These errors are showing in the log: not, but I have “403 forbidden” if I try to do the update

Steps I have tried to fix the problem:
I have tried to use Composer and Notification Update, but I don’t have any solutions.
I ask you if I can do a backup of the database of the 4.1.0 Mautic installation. After doing a new Mautic 5.x installation and after restoring the backup of the Mautic 4.1.0 into the database of the new Mautic 5.x installation.
I want to use the new version of Mautic, but I don’t want to lose all the data from the old database…

Hi,
I have tried the following solution to update from 4.1.0 to 4.4.11, after the Mautic update I edited the .htaccess and now I don’t the 403 forbidden error message, but I have another error message that I cannot display the login form…

Do a full backup of source and database, then try to update mautic using CLI,

see this for detals:

Hello, I’ll try this on my instance to see if can have upgrade with CLI.

Usually when tried to upgrade from GUI I got this frustrated 403 forbidden error. Which I had to rollback after on previous version. I’d like to have the latest, but somehow to overcome this trouble.
