Title: Payment problems Last modified: August 21, 2016 --- # Payment problems * Resolved [Fregatt](https://wordpress.org/support/users/fregatt/) * (@fregatt) * [13 years ago](https://wordpress.org/support/topic/payment-problems/) * Hello! * I’m trying out Marketpress Lite and unfortunately I’ve come across some problems. * First problem is to setup payment methods. I’ve decided to try PayPal Express Checkout. I’ve filled in all my API details that I’ve got from my PayPal account. When I try to make a test order and get to the part when I can choose between the two options I’ve got (“Manual” and “PayPal”) I get this message from clicking“ PayPal” : * “There was a problem connecting to PayPal to setup your purchase. Please try again.” * Any suggestions how to fix this? * Next question is if it is possible to add other payment solutions even thought I’ve just got Marketpress Lite. I would really like to add the ordinary PayPal functions (so customers don’t need to log in to PayPal to pay as I understand is required in PayPal Express Checkout). Can I do this manually? * I also need to add other payment solutions, with special descriptions and an extra fee. I have no idea how to do this! * Thank you so much for reading and hopefully helping me out! * [http://wordpress.org/extend/plugins/wordpress-ecommerce/](http://wordpress.org/extend/plugins/wordpress-ecommerce/) Viewing 8 replies - 1 through 8 (of 8 total) * [Ari Stathopoulos](https://wordpress.org/support/users/aristath/) * (@aristath) * [13 years ago](https://wordpress.org/support/topic/payment-problems/#post-3748819) * Hello there [@fregatt](https://wordpress.org/support/users/fregatt/), * > “There was a problem connecting to PayPal to setup your purchase.

Neither of them seems to work. * I’m not sure what you mean by multisite installation, I don’t think so… * Thanks for answering my post 🙂 * [Ari Stathopoulos](https://wordpress.org/support/users/aristath/) * (@aristath) * [13 years ago](https://wordpress.org/support/topic/payment-problems/#post-3748845) * Could you please post the **entire** message you get?

Please try again.” * [Ari Stathopoulos](https://wordpress.org/support/users/aristath/) * (@aristath) * [13 years ago](https://wordpress.org/support/topic/payment-problems/#post-3748872) * This could be caused by a number of reasons…. It could be invalid user address, not allowed action in your country, wrong API credentials and a bunch of other things as well!
