All forms not working

Hi there,

This is a strange issue that has suddenly come up.
When i uploaded, i checked the contact forms on each of the pages, from my laptop and from my mobile, all were working fine...i was receiving all the emails...but suddenly they are not!!

i have checked the coding, even copy pasted to make sure the contact form code is exactly the same on all the pages, the same form.php file, but for some strange reason, it works on some but doesnt work on others and im just not able to understand why.

Example, on these pages the contact form works:
http://www.cosurvivor.in/pages/destinations/enter-spiti-valley.html
http://www.cosurvivor.in/pages/destinations/camp-ganga-riviera.html
http://www.cosurvivor.in/pages/destinations/chopta-valley.html

but the same form on these pages does not work:
http://www.cosurvivor.in/pages/destinations/discover-ladakh.html
http://www.cosurvivor.in/pages/destinations/discover-spiti-valley.html
http://www.cosurvivor.in/pages/destinations/discover-ladakh-flyin.html

its exactly the same form, same code, only changed the subject line...it shows the confirmation message but for these pages only i am not receiving any emails in my inbox...im getting emails from the other pages...is there any reason why this could be happening.

I've been promoting this page on social media and am afraid i might have lost a few contact requests...would really appreciate any help with this.

Thank you.
