problem with bolt

Hi, right now i’m having a problem with bolt on my blog http://www.todosobreseriestv.com/.

I don’t know why, all the words of all the topics are in bold. Also if they don’t have any bolt activation. If I open the post in the preview I can see as it has to be, but when i publish it, it convert to bolt all the words.

The problem has just started, as 2 hours ago, was all correct.
