Andriod showing errors

I have an LG, when i access the home page it gives me an error

This page contains the following errors:
error on line 286 at colum 8: Opening and ending tag mismatch
Below is a rendering of the page up to the first error.

Can anyone tell me how i can fix this. Don't know where to look.

thanks

What is url of this page?

www.mehfilekhorasan.org

Looks like the article "Donate to our Cause" has opening div tag that never closes. Check its html source.
