Ajax Load More is not working properly

Hello,

i recently install Magazy template which has the Ajax Load More plug in, but in my server is not working properly. The site is newslike.gr, you can see which is the problem.

I test this in another server and is working, but i cannot find a solution to this specific server that i want to have this site.

Can you give a guideline which my be the problem? I already had spoked with the template authors and my hosting support department, but nothing yet.

Thank you a lot in advance.
