**Your software** My Mautic version is: 4.4.7 My PHP version is: 8.0 **Your problem** My problem is: Tried to install “custom objects” plugin from the marketplace. Takes a while, confirms installation. Asks for activation in plugins. However, its not in the plugins section, can’t be activated. Is also not showing up anywhere in Mautic. The plugin folder doesn’t show this plugin either. These errors are showing in the log: “[2023-04-01 15:17:23] mautic.ERROR: Installation of plugin through Composer has failed” Steps I have tried to fix the problem: Tried to install from CLI via “composer require acquia/mc-cs-plugin-custom-objects” confirms the installation. Clear cache, install plugin via command line made it finally appear in the plugins list in Mautic. ---

I had this issue after installing Mautic with Composer and I thought I did something wrong so didn’t bother to report it. ---

I think I have the same problem: **Your software** My Mautic version is: 4.4.7 My PHP version is: 7.4.33 **Your problem** When I try to run the installation of any addon on, the information appears: “Successfully installed Cronfig” My mautic is a fresh test installation.

Hi guys, Any solution for this issue? Fresh install through composer, I installed the plugin from Marketplace and then I’m stucking with a 500 internal error just after hitting the button to go to the plugins page (CTA after install is successful).
