Support for multilanguage sites, Internationalization (I18N)

Code:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function '' not found or invalid function name in /var/www/web40/htdocs/......./admin/load.php on line 39

Looking at that line 39 seems you have a problem with a plugin. Did you delete it but is it still there in your calls ? Changed a name or path maybe and now it cannot be found ? Deactivate all plugins one by one and see what happens.

well, first to identify that the problem lies in the i18n-navigation I replaced the call 

PHP Code:

<?php get_i18n_navigation(return_page_slug()); ?>

with

PHP Code:

<?php get_navigation(get_page_slug(FALSE)); ?>

now I get a menue with all pages (which is ugly), so it must be something with the hierarchical navigation.
The page list still does not load...

I will deactivate all plugins..
