In order to use the debugger you need to modify the php.ini file of the Apache server you are using. Follow these instructions here

  • open up this file with your favourite text editor
  • do a search for xdebug you should find something like this:
;; Only Zend OR (!) XDebug

Delete the ; in front of the text under ';; Only Zend OR (!) XDebug' so it reads like this:

;; Only Zend OR (!) XDebug

Then do a search for implicit_flush you will find

implicit_flush = Off

Change the Off to On

implicit_flush = On
