PayPal Checkout Error

Hi there,

Thanks for last update. It fixed all previous tickets I had ( by xx ) and the side panel is working properly and everything.

Except just one thing..

I want to use PayPal (not stripe, etc) only as checkout.

1. I put my PayPal Email Address in Projects/Funding/Fundit Settings
2. I don’t put anything in the PayPal API Credentials (left as sandbox)
3. User PayPal Address was set properly (campaign owner)

When doing a small contribution, I’m getting:

Please wait while we process your transaction..

Fatal error: Uncaught exception ‘PayPal\Exception\PPInvalidCredentialException’ with message ‘Invalid userId ‘ in C:\wamp64\www\wp-content\themes\fundingpress\funding\lib\paypal\paypal-sdk-core-php-811c13c\lib\PayPal\Core\PPCredentialManager.php on line 144

Also on the side, I used other crowdfunding engine (Joomla) and I just put my PayPal address (business PayPal) and I’m getting fund. I didn’t specified any API settings
Application ID, API Username, API signature…

Do I need to specify all that? Where do I get those info?

Thanks!
