Hello, I can not write on this topic (https://support.bloxby.com/forums/topic/bug-after-successful-payment-via-paypal/) because it is closed. Thats why I opening new one.

I found the problem about error 500. The problem was that the server didn't has a timezone="" setting in php.ini

Now I have another problem. When I click on "Pay" link in bloxby, the system is  redirecting me to PayPal. After this I am logging in with my PayPal account and I accepting the payment. Then PayPal is redirecting me again to my website an there is an alert that I have paid successful and my Account is not established. When I check my Bussiness PayPal Account, there is not any transactions. Could you check that problem. I think that is good to test Real payment on bloxby packages.
