Hello,

I've installed the plugin and tried the configuration however i keep getting an error message saying that the client secret is invalid. I deactivated-activated the plugin several times with no help.

I believe that the issue is related to the fact that the plugin attempt to modify the header with no success.

When I hit authorize i get two warnings:

Warning: sprintf(): too few arguments in /home/.../theme/.../framework/version-check.php on line 158

Warning: cannot modify header information - headers already sent by in /home/.../includes/misc.php on line 1126

Thank you in advance to any who could help me to solve the issue.
