Any news?
Was ist caused by wrong login credentials?
I get the same error.
Credentials are verified and correct.
New installation as I’ve been trying to get started with this plugin but am facing a variety of errors.
Also an error with weight. T
The plugin does not accept decimal numbers, whether with a point or a comma.
Error message: Please enter a valid weight.
We now checked several possible other issues by deactivating all other payment methods and all unneeded plugins but still same problem so the problems seems to be caused by Smart PayPal Checkout.
