UPDATE: FIXED
Ran following commands on my machine:
1 .Fist login as root user in your mysql.
sudo mysql -u root
- Replace
mautic-database-name
with your own mautic database name and run this in mysql interface:
USE mautic-database-name;
- Print widgets table:
SELECT * FROM widgets;
- find out the ID of the widget that is broken and update its params, in my case the ID of the widget was 7, so:
UPDATE widgets SET params = "a:0:{}" WHERE id = 7;
that’s it!
cheers!
