I am trying with https://github.com/Varying-Vagrant-Vagrants/VVV to get running vDebug.
The issue is with this very basic settings:

let g:vdebug_options = {
    \    'break_on_open' : 0,
    \    'ide_key' : 'VVVDEBUG'
    \}
let g:vdebug_options.path_maps = {"/srv/www/": "/home/mte90/Desktop/VVV/www/"}

I see the page on loading and after a while open as show in the screenshot without any way to interact with the information.
It's not clear to me what is missing to get working everything.
If I use other tools the connection and debugging is working.
