Sorry, forgot to mention earlier that I have tried with all types of browsers and all of them face the same thing. I have other sites as well and those are OK so it looks like the problem is specific to this particular one but I do not have a clue what could be the problem.
Sorry, this was an issue with one of the plugin I installed. After replacing the plugin with another one, everything is working as normal.
