Yes, I’ve got it back!
After my ssl certificate provider startssl.com upgraded the root certificates with the power of
SHA256withRSA instead of
SHA1, I’ve got my A+ rating for SSL secured websites back.
Here the link for verification: https://www.ssllabs.com/ssltest/analyze.html?d=mmo.to
With the upgrade of my account at startSSL on May, 28 I could create a new certificate which gained all the benefits of the upgraded signature algorithm, so to say, not rated ‘weak’ anymore. 😀
Why I did not check my rating earlier? Well, lazy?! Other more important tasks to do?! 😛
