Hello to all.
I have a problem with installing plugin -architecture. At the first time, I installed Cacti and he worked correctly. But then i have installed a plugin architecture and now one error appeared error "Fatal error: Call to undefined function api_plugin_hook_function() in /usr/share/cacti/site/lib/functions.php on line 1414"

Line 1414 in functions.php:
$nav = api_plugin_hook_function('draw_navigation_text', $nav);
Help, please. How can i fix this bug?

version of cacti 0.8.6j-1.1ubuntu0.3
cacti-plugin-0.8.7b
OS Ubuntu 7.10

Cacti 086j is fine. But matching PIA would be 1.x
If you use latest Cacti087b, PIA 2.x matches
