    Hi, azlistings, 

    In order for you to resolve this issue, here's what you can do.

    First, make sure you are logged in properly with your Paypal account. The Security Error means that there is something wrong with your Paypal login information. 

    You may need to try to re-enter your login information. If you're copying and pasting this information, please make sure that there are no spaces copied, you may try to paste it first on a notepad just to make sure. (Sometimes, copying and pasting text includes a single space at the end without you noticing it)

    Also, just to add, please make sure your Paypal is not in Sandbox mode. 

    If you need further assistance, kindly let us know and we will be glad to help you anytime. 

     

    Thank you for using JotForm.

     

     

    Kind regards.
