Try fixing your database schema. Go to http://[your-mautic-url]/s/update/schema. It will update your database schema if there are some known updates to be applied. I had the same problem, and it works fine now. If it still fails, try looking at the general troubleshooting in the docs [https://mautic.org/docs/en/tips/troubleshooting.html](https://mautic.org/docs/en/tips/troubleshooting.html) ---
