Sorry for my English as I'm working on a project to manage a CRM, I changed the index.php file in my test environment for the real environment, to run and go to the website I figure the error (error 500 internal server).
They are all correct permissions on my virtual server.
I go back to change the index.php file which originally had (the original file is in HTML). and no problem, directs me to my local server page.
I do not know where my failure.
Thank you so much.
send original file (running)
