see the screenshot http://prntscr.com/htsh3h

when i click instamojo  button It showed  like "There is problem with payment button, please try again later."

After asked support to instamojo they replayed as
"I had gone through your website.
Could you please let me know how you have integrated Instamojo with your website as the plugin that you have used is not an official plugin developed by Instamojo"

@nijamutheen
Instamojo API is used.
Please go to index.php (in plugin).

Change:
define('OSP_DEBUG', false);

Into:
define('OSP_DEBUG', true);

and try payment again. It should mail you details of payment with problem. This error is shown once incorrect payment details are sent to instamojo.

Now also getting error

@nijamutheen
Of course, objective is to get that email and it's content
