After posting the last post, which was about 24 hrs ago I found that the blog was down for about 8 hrs. The problem occurred mysteriously and the reason why that happened is still unknown to me but this is what happened.
Our homepage didn’t appear although individual posts were appearing with the default blog design. The problem was related to the blog design files which went down from the backend as well. I tried several things to fix the issue like checking the file permissions and verifying the files but nothing happened.
I raised a ticket with the host and took a complete backup of the blog but to my surprise the blog went up and live after I woke up in the morning and was about to restore it to earlier data. TS regret inconvenience caused but we are back to provide our services.
