I am using a self-hosted Mautic application. These are the steps I accomplished:
- Navigate to Settings \> Manage Addons
- Click Install/Upgrade Addons
Initially, the list auf available addon groups is downloaded/created
- Enable addon group CRM Integrations
- Drill down into CRM Integrations
**=\>This produces an application-internal error 500.**
- Navigate to Settings \> Manage Integrations
**=\> This produces an application-internal error 500.**
Any ideas?
