Problem with bottom post links

Hi, first of all thank you for the theme!
I’am currently making a new site and I desided to use your theme.
I’ve installed a plugin named Ad Inserter and placed an adsense code to appear in the end of each post, wright after the text. The ads appear properly but the links (ex. next post, previous post, wp pagelinks…) wont work at all!

The same thing happened when I disable the plugin and used another one.

Could you please help me out with that?

Thank you in advance!
