I found out that this part of the module gives me a problem during installation:
$response = json_decode($json); if (is_null($response) && json_last_error() !== JSON_ERROR_NONE) { $response = $json; }
Mainly this part
$response = $json;
If I remove that single line, I can install the module. I put it in again, since it is need for the check of json later on.
I just don't get why this snippet is giving install problems? Escpecially Override conflicts.
