As a test i created a new php project (because the project i tested it before was a large project).
I changed php version to 7.2 and i put just this code:
echo 'Hello Framework!';
var demo = 'test';
var demo2 = 'test23';
As soon as i start debugging with Script Debugging enabled, chrome starts but 90% of the time stays at this url: (about:blank) and i get the messages.
Only sometimes it continues to the localhost ip with working output.
I am using Google Chrome Version 72.0.3626.109 (Official build) (64-bits)
