Hello,
I noticed for GPLI 11 that the plugin treeview has invalid relative includes in its public files.
In both files:
marketplace/treeview/public/index.php
marketplace/treeview/public/left.php

the following line is used:

include(../../inc/includes.php);

This fails with the warning:

PHP Warning: Failed to open stream: No such file or directory

Suggested fix: update the include path to be relative to the current file, for example:
include(../../../inc/includes.php');

This way, the plugin works properly when placed in marketplace/treeview.
Thanks!

Hi @seblveb

Thank you for your feedback, the includes are no longer useful and I have removed them.
