Indeed,
when i check
https://www.sslshopper.com/ssl-checker.html#hostname=ethereumwallet.orgit tells me the following:
The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate. Learn more about this error. You can fix this by following Comodo's Certificate Installation Instructions for your server platform (use these instructions for InstantSSL). Pay attention to the parts about Intermediate certificates.
Let me purchase a different SSL. I will be back to you shortly. Would you like to have a few ETH or a few mBTC as a small thank you?
