Error 500

Hi I have installed theme online, fresh no content and created a single campaign.

Have created Paypal API details, App details as I have attached.

But have encountered errors, after the “Commit to purchase” it goes to Server error (Chrome), blank page (Safari) and blank page (Firefox)

I have also tried on my local MAMP, same exact error. I have checked “curl” it is  enabled (as I have checked other thread before posting)

Anyway I guess it’s best to have a look on the screenshots so that you have a visual of the activities and the error itself.

I hope to put our site live, I will try other crowdfunding themes if this theme really does not work at all, I hope you could help.
