I don't know if this is a Suffusion problem, but I get this warning from my server error log :
PHP Warning: call_user_func_array() [<a href='function.call-user-func-array'>function.call-user-func-array</a>]: First argument is expected to be a valid callback, 'suffusion_before_end_content' was given in /home1/esoundsc/public_html/astrablog/wp-includes/plugin.php on line 403
Am using Wordpress 3.4 and latest Suffusion, but this warning has been around since Feb 23, 2012 and just keeps recurring.
Line 403 in current WP 3.4's wp-includes/plugin.php is called from function do_action($tag, $arg = '')
In this code :
foreach ( (array) current($wp_filter[$tag]) as $the_ )
if ( !is_null($the_['function']) )
call_user_func_array($the_['function'], array_slice($args, 0, (int) $the_['accepted_args']));
} while ( next($wp_filter[$tag]) !== false );
Is this a Suffusion issue, or something else ? Just wondering ...
