Server 500 during installation

Hi guys, Excellent work here. Could you please help me install it though? I think I know a little about Drupal but unable to install a copy of Opigno on a VPS. I have a local phprc file with the values given in the documentation here. I still get this at Module Organic Group I think number 54 during installation: " An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: www.domain_name_removed.com/install.php?profile=opigno_lms&locale=en&op… StatusText: Internal Server Error ResponseText: 500 Internal Server Error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, webmaster@domain_name_removed.co and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request. " Can you help or give me an indication? I believe it is a PHP.ini value problem. If someone can list all the values that need to be set, I will try again. Kind regards Hiwa
