Facebook links – and HTML tags in the message

Hi

when I push share button and want to share my post on facebook the window where I am going write somehting about the post – it says something like this:

You may use these HTML tags and attributes: <?a href=”” title=””> <?abbr title=””> <?acronym title=””> <?b> <?blockquote cite=””> <?cite> <?code> <?del datetime=””> <?em> <?i> <?q cite=””> <?strike> <?strong>

instead of some tekst from my blog

Is it a plugin that make this impossible?
