PayPal API incorrect

Hi Skywarrior!

Thanks for building a superior crowdfunding theme! We’re enjoying it, but we’re still having trouble processing donations with PayPal (WePay is all good). After committing to funding a campaign, I’m directed to a blank, white page.

I suspect it’s an error with my API credentials since I’m getting this error message:

“PHP Fatal error: Uncaught exception ‘Exception’ with message ‘Preapproval failed: Authentication failed. API credentials are incorrect.’ in /home/instrup6/public_html/wp-content/themes/funding_press/funding/paypal.php:100”

However, I am almost 100% that I have all of my production PayPal API credentials correct (straight from PayPal.com).

Here is a link to our site: http://www.instrumentl.com/v2/

Please advise!

Thanks!
Angela
