Cannot reproduce the alert when following the tutorial (drop database)

[RGijsberts]

Hi, I've installed the msp/shield module for a client and configured/enabled it. When I type " ; drop database magento " as shown in the tutorial I get no error message.
Instead, it just redirects me to the search results page.

What am I doing wrong?

Hello @RGijsberts ,
we are not supporting the alert page anymore for security reasons.
You should get a fake 500 error as protection page.

Hi @phoenix128 , pardon the delay in my response and thank you for your reply.
I am not getting any feedback after installing and configuring the module. After I type ; drop database magento and hit enter it redirects me to the search results page.

this is a Magento 2.2.6 site by the way.
