Error at Login - "The action you requested is not allowed

Many thanks for your suggestions luckmoshy.

This worked!! :-)
php spark cache: clear

It is stange because sometimes login and sometimes now. As the above command worked, will monitor it to see when/why *if* fails again.

When you say, turn off CSRF, you mean it would be better to implement manually?

You mean I should also try by *adding* // in front of the route and not using routing, as a test?
