Wepay

Hi Team!
I like your theme a lot!!! I had a problem couldn’t figure out a couple days now would like to ask for your help.

On my Wepay say:
Fatal error: Uncaught exception ‘WePayPermissionException’ with message ‘could not parse authorization header, a valid access_token is required’ in /home3/zubu555/public_html/sponsorsquare.com/wp-content/themes/funding_press/funding/lib/WePay/wepay.php:268 Stack trace: #0 /home3/zubu555/public_html/sponsorsquare.com/wp-content/themes/funding_press/funding/lib/WePay/wepay.php(290): WePay::make_request(‘preapproval/cre…’, Array, Array) #1 /home3/zubu555/public_html/sponsorsquare.com/wp-content/themes/funding_press/funding/funding.php(507): WePay->request(‘preapproval/cre…’, Array) #2 [internal function]: F_Controller->action_template_redirect(”) #3 /home3/zubu555/public_html/sponsorsquare.com/wp-includes/plugin.php(525): call_user_func_array(Array, Array) #4 /home3/zubu555/public_html/sponsorsquare.com/wp-includes/template-loader.php(12): do_action(‘template_redire…’) #5 /home3/zubu555/public_html/sponsorsquare.com/wp-blog-header.php(16): require_once(‘/home3/zubu555/…’) #6 /home3/zubu555/public_html/sponsorsquare. in /home3/zubu555/public_html/sponsorsquare.com/wp-content/themes/funding_press/funding/lib/WePay/wepay.php on line 268

My theme version is 3.9.2
