Page with parameter not rendering CSS

Question

Hi, I have a problem rendering my page. When I do a route with parameter in the URL the bootstrap css simply does not render, however, if I do a route that does not have any parameter in the url the css is normally loaded.

app.get( '/encontrista/:idEncontrista', isLoggedIn, function( req, res )
{
    res.render( 'signup.ejs', { message: req.flash( 'message' ) } );
} );
