Hey saleem,

I am really sorry for the delay of this reply as it is a public holiday for us here.

Try take a look of this page and see is it enabled this from backend > Easyblog > ACL > select your user group (example : public/guest user group) > comment tab > Post Comments -YES

If the comment form still can't appear, can you provide us with your Joomla backend and FTP access so we can better have a look?
