Impossible to change shpping settings configuration when module is installed

[GardeTV]

Description

I installed MSP_Dev_tools on my magento 2.1.4 as described in your guide:

https://github.com/magespecialist/mage-chrome-toolbar#installing-on-magento-2

When I enabled profiler feature through .htaccess all works fine, but when i try to change my shipping settings in:

Stores -> Configuration -> Sales -> Shipping Settings

Magento redirect me to the bashboard.
I did a little debug and i found a broken ajax call before redirection. It would be possibile that this issue is in someway related to bugfix #9?

All works if I comment

SetEnv MAGE_PROFILER MSP\DevTools\Profiler\Driver\Standard\Output\DevTools

on my .htaccess.

Issue confirmed while using profiler. We are fixing it.

Found as Magento bug.
I just reported here: magento/magento2#8890 .

Meanwhile we found a workaround using index.php modification instead of SetEnv.

Edit your index.php and pub/index.php and put this at the very beginning of PHP code:

$_SERVER['MAGE_PROFILER'] = [
    'drivers' => [['output' => 'MSP\DevTools\Profiler\Driver\Standard\Output\DevTools']]
];
