Think the problem is the www. in front of store domain which is not the same as the ssl certificate (no www. ) which hasn't changed since issue but the problem has now just emerged with the update. Is this possible

Hi,
Have a new error which I have never seen before and don't quite understand as everything in settings seems correct. any thoughts.  Not sure why the store URL has a mail. in front of it in the error.

Check setting of your store domain URL in System Settings. Loading default store configuration for now. in /home/safetysnap/public_html/Store/core/lib/config.php on line 228

hi,
Does anybody have the fine details on the installation of the square extension. must be doing something wrong because I am getting connection errors

  Connection to Square server could not be established. . Check your server configuration or contact your hosting provider

I have SSL certificate on server

Thanks
