vbWiki Pro does not properly get the global variables $first_navbit, $bitters, and $last_navbit
As a result, if you try to modify navbits for a wiki article, you will get a "This style has not been updated for Custom Navbits" error, even though you have made the correct updates. In order to workaround this strangeness, vbWiki Pro users should add the following plugin (this requires vbWiki Pro hooks which is why I am not including this in the product).
Product:
CES Navbits Designer
Hookname:
vbwikipro_before_navbits
Title:
Navbits Globals
Phpcode:
PHP Code:
global $first_navbit, $final_navbit, $bitters;
