Re: Cannot call WP functions inside BB, followed docs instructions…
include_once for that matter) need a path to the file rather than a URL. A path would be like the addresses you get when you’re browsing folders on your computer. I can’t say what your path would be, but mine is
/home/username/public_html/wordpress/wp-config.php. Ask your hosting provider if you don’t know what to use.
It might be easier to recreate the theme anyway, if I remember rightly a fair few folks come here with problems when trying to stick bb into the WP theme like that.
