conflict with a plugin

Hello,

I want to use your plugin on my website. But I my post pages does not load when ever I activate simple facebook connect and Yet Another Related Posts Plugin. I have modified this plugin a bit and I have added catch_that_image() function in Yet Another Related Posts Plugin. Now these both plugins does not work together. Please tell me any solution.

This is my website: https://www.monkeygag.com/

Thanks
