PhpStorm + Xdebug: Connection established, no Debug window popup in PhpStorm

Question

I\'m struggling to get PhpStorm and Xdebug to play nicely on a specific Vagrant VM.

How can I effectively track down and resolve the issue in connecting PhpStorm

Answer 1

You are using PhpStorm 2018.2.x with Xdebug 2.7.

Either upgrade PhpStorm to the latest stable 2018.3.x or downgrade Xdebug to 2.6.x

The problem is in recently changed XML namespace in Xdebug protocol, as of Xdebug 2.7 (https instead of http). It's fixed/supported since PhpStorm 2018.3.0 (see WI-43622).
