Frog CMS

Hi, I just wanna say that Frog rocks! But, I'm here for a little bug.. =S When I edit something (article, page, user, etc...) I get an Blank page in every time. And then when I turn back to Admin Dashboard it says that the article, user or other content has edited succesfully.

This is an redirection problem of the core script (wrong configurated) or my server doesn't support some feature?

Thanks! Greetings.
