Check your custom html/css widgets. Is there any javascript code?

i add a like and twitter button...

try to remove it one by one. Find out which widget crashes and remove it.

hi... i remove facebook like button. and now no error show (sorry for my english)
how i can put my button?

Seems there are some JS conflicts with FB botton. Would you attache html code of this botton?

best way to attach is to paste the code into notepad, save as a *.txt file and attach to the forum. Pasting code intot eh forum post may not display the best.

ok. i delete de code but this code is generated in http://developers.facebook.com/docs/reference/plugins/like/
