Good news KEN I finally found the culprit (like you talk-me into your last reply) and one solution…
After many hours of investigation and after activated the “Display Errors” into the PHP settings…
The SSL certificate from my web hoster it’s not validate by EC , so I replaced all reference to HTTPS by HTTP into the ec-radar.php and now everything is OK.
The next step will bee to talk with my web hoster about their rejected certificate.
Again, thank for your work and your excellent support.
