[wp-hackers] My plugin doesn't work online :( Shortcode loading order?!

[Diana K. Cury]

Sorry for bother,

I just can't understand why my plugin isn't working, the post type screen is ok, but the shortcode action does'nt work at all.

When adding [mensagem], it supposed to add the form into the page, but anything show up when doing so :(
