debugging errors.. how to remedy?

Replace get_bloginfo( 'siteurl' ) with home_url().

As the get_bloginfo() Codex entry explains, siteurl is deprecated:

'siteurl"https://wordpress.stackexchange.com/"home (note this is deprecated! from version 2.2)"https://wordpress.stackexchange.com/"url' – Returns the 'Site address (URL)' set in Settings > General. This data is retrieved from the 'home' record in the wp_options table. Consider using home_url() instead.
