I’m setting up my first product on [http://www.diycollegerankings.com/product-listing/]. I can add the product to the cart but when I click on Checkout, I just get a blank page in Firefox and the message “HTTP 500 error
That’s odd… the website can’t display this page” in Edge. I’m not using the Fancy Redirect. I don’t know what to try next. Thanks for your help.
You will need to get your hosting provider to look at the server log and see why the server is failing to execute the request. We can then go from there.
Please have a look at the following post which should be helpful:

I tried installing a clean plugin, no change. I found the error log and this is what is being reported:
PHP Fatal error: Cannot redeclare class Paypal in /home/diycollegerankin/public_html/wp-content/plugins/wp-cart-for-digital-products/lib/gateway/Paypal.php on line 5
What version of PHP is running on your server?
PHP 5.6
Looks like you have another plugin thats using the same class name (Paypal) so its conflicting.
Please do the following test to see which plugin it is conflicting with on your site:

WPDM – Premium Packages was the problem. Thanks!
