pepramon

Works fine with the version: v5.4.2

It's fixed now... I don't know how but now it's working !! Thanks !!

Live

Changing the api keys gives me the same error !

Yes !! Before updating the Paypal it works fine....

All the versions give me the same error: Authentication failed due to invalid authentication credentials or a missing Authorization header. But also when I try to uninstall totally the paypal module I can't because when I reinstall the module all the previous configuration was saved. On the other hand if I try to uninstall or delete the module completely from the back office it gives me the error 500.

don't work. I'm sorry.... the same error appears !!

The problem is that I can't delete completely it gives me Error 500, there is a manual method to delete the module ? I use live method !!

The problem happend with the new and the old version. Probably the best is to delete all the settings and begin again configuring PayPal it's possible ?

Probably something is corrupted outside the module....

It gives me the same error and still when I try to uninstall or delete I receive a 500 error.... which is strange....

I've refreshed the credentials and the error persists....

Also if I try to uninstall the PayPal module give a 500 error

I received this only in the front office when I try to pay by PayPal....

After upgrade the Paypal I receive this error: Authentication failed due to invalid authentication credentials or a missing Authorization header.
