Hello Francesca,

Can you please tell me did you disable Sandbox mode?

If you leave it in the Sandbox mode, live transactions will not work.

Or if you are set to Live Mode,

please check your Live Client ID and Live Secret on your PayPal account? 

Let us know if that solves the issue.

If you already checked all of this, and still can't isolate the issue,

with your permission, we can try our own PayPal Test on your site,

and then we will revert everything as it was?

Please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.
