I have a problen with the payment mode Cyberplus banque. I installed the extension, changed the chmod of request and reponse files and put them with param.xxxx et param.xxxx et certif.fr.xxxx under lib/atos .
but in the test i have this erreur :
Error reading certificate file (/home/f66196/public_html/magento2/lib/atos/certif.en.038862749811111)
But the probleme that i installed a “certif.fr” and I don’t understand why he look for “certif.en”
Please help me to resolve it
