Forms not working after mautic update to 4.1.0

I was never able to fix this, so I deleted that installation and am beginning from scratch again.

Is it possible for a no-code person to use this software DIY? Or does it require coding knowledge to use it effectively?

I am facing a similar issue when updating a certain instance to 4.2.1 (post here: Upgrading from 4.1.0 to 4.2.1 Mautic Died - #2 by mikew)

I have tried the alter table you have suggested however an getting the following error from mysql

MySQL [defaultdb]> ALTER TABLE leads ADD column generated_email_domain VARCHAR(255) AS (SUBSTRING(email, LOCATE("@", email) + 1)) COMMENT '(DC2Type:generated)';
ERROR 1054 (42S22): Unknown column '@' in 'generated column function'

I am running mysql 8 over here.

Any help will be much apprecaited
