 * 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.

 * While configuring your plugin, ensure you have entered the correct information
   in the Domain field. Select the region in which your Zoho account is hosted (
   in, com etc).
 * Verify if the Client ID and Client Secret used in the configuration page matches
   with the Client created for the plugin in Zoho Developer Console.
 * If all the above-given troubleshooting methods do not resolve the issue, reach
   out to our Customer support address ‘support[AT]zohomail[DOT]com’ with the screenshot
   of the configuration settings page for a solution.
 * Regards,
    Cynthia

 * Dear Cynthia,
 * I confirm to have done all configuration as described by you.
 * I have contacted the support already one week ago, I was asked availability for
   a telephone call which I did immediately but I received no call. Could you please
   make sure that my ticket is still open and somebody will call me or further contact
   me to solve the problem?
 * Thank you.
 * Fabio.
