Installing mautic 4.x

[Grienauer]

@girish how can a cloudron user install the latest mautic Version? By default, the 3.x is used and not 4.x on the app Installation overview page.
thx for clearing this.

@grienauer mautic 4.x package is not working. It was initially blocked by https://github.com/mautic/mautic/issues/10453 which seems to be fixed now but the Cloudron package is still error'ing despite the above fix. Let me look into again, I think we have to report it upstream as separate issue.

To give an update here, I am able to make 4.x work in the LAMP app. So, it seems there is some issue in the Cloudron app packaging. Investigating.

OK, it seems to be some bug in the LDAP module - https://github.com/Monogramm/MauticLdapAuthBundle .

I found the root cause. The LDAP module uses nullable booleans (i.e a bool value can set to null apart from true/false). This worked in mautic 3 but there is some regression around this in mautic 4.x - https://github.com/mautic/mautic/issues/10711 . They merged a changed recently that fixes this at https://github.com/mautic/mautic/pull/10716

https://github.com/cloudron-io/MauticLdapAuthBundle/commit/961666a4c491d5e4f0681229419117f84dff007d is the fix

So, all our mautic instances updated fine. Some of the themes might have to be removed manually since it seems the config.json changed from mautic 3 to mautic 4.

If some pages error, check the logs in System info i.e the Logs view in https://mautic.domain.com/s/sysinfo. You might see an error in the logs like so:

[2022-01-25 15:07:18] mautic.CRITICAL: Uncaught PHP Exception Mautic\CoreBundle\Exception\BadConfigurationException: "Theme Blank not configured properly: builder property in the config.json" at /app/code/app/bundles/CoreBundle/Helper/ThemeHelper.php line 673 {"exception":"[object] (Mautic\\CoreBundle\\Exception\\BadConfigurationException(code: 0): Theme Blank not configured properly: builder property in the config.json at /app/code/app/bundles/CoreBundle/Helper/ThemeHelper.php:673)"} []

To fix the above, open the file manager:

• Go to themes directory
• Delete the blank-grapejs and confimme (sic) theme directories. You might have to delete more directories depending on the error messages you see. The above error gives a hint as to what theme is causing a problem ("Theme Blank not configured properly")

Thanks @luckow for helping us debug.
