Hello,

Please check server requirements in the documentation.pdf, pay attention on MySQL mode `only_full_group_by` It must be disabled.

Thank you

I have teh same problem, I did unabled the only_full_group by mode in the MYSQL server and I still got this error

Hello,

If you have already checked the server requirements and MySQL only_full_group_by mode is disabled then you need to check your server error logs and let me know the error details so that I can suggest.

You can enable app logs by changing the `log_threshold` to 1 in `app/config/config.php` and then visit the page again to reproduct the error. Lastly check the latest log in the `app/logs/` folder.

Thank you
