Please Report Any Post Bug

After I updated Math and Multimedia to WordPress 3.5, I found several of my posts contain the boxed code error below. I found a way to fix this error, however, I have to go to the post individually and make necessary changes.

WordPress 3.5 bug?

While I’m still finding how to fix this error universally, if you see any post with the same error, kindly paste the link of the post in the comment box below and click Post Comment to inform me.

Thank you.
