Support Error initializing paypal communication

[Bari]

First sorry for my English but I only speak German and use the Google translate.
I try since RM Marketplace for XF 1 to set up but have not worked it out although I read the manual I am now desperate and angry that it does not work I do not know how to continue it is complicated and I'm now unfortunately again a lot of money Pay for me to seek another solution from German developers because German users of Xenforo are not appreciated.
Goodby

We can speak English and French, unfortunately German is a second language I learnt but didn't recall a lot

Have you configured the PPConfiguration.php file and moved it to the location stated in the user manual ?

Do you have any error in the log of your forum ?

What kind of paypal account do you have ? Standard, business, premier ?

Do you have percentage on sale active ?
