Thank you Jota, It has got to something with the theme, since yesterday I have been using different theme and the results have been consistent. Time to load has been less than 2 sec previously it was 14 sec. YSlow has jumped to positive which never crossed 67.
Instead of opening different ticket I am asking my question regarding renewing cert here itself.
I do not remember which email address I have used for registering the certificate on my site, also the domain list. Can you please let me know how to get the email address and the list of domains I have used?
If using multiple versions of the domain, should I separate y ','?
