@ahmadbadpey Did you ever solve this?
I have the same problem. I also uncommented always_populate_raw_post_data = -1 in php.ini both in C:\wamp\bin\php\php5.6.31 and C:\wamp\bin\apache\apache2.4.27\bin. After restarting Apache I still get the same error messages. I can log in to my application, but parts of it isn't working and I don't know if it is because of this.
Using Windows 10.
