 * Hi together,
    this is the error, that wordpress display at the bottom of my site
   [http://www.ecoevent.de](http://www.ecoevent.de): Warning: call_user_func_array()[
   function.call-user-func-array]: First argument is expected to be a valid callback,‘
   Array’ was given in /mnt/web1/63/84/536484/htdocs/WordPress_03/wp-includes/plugin.
   php on line 405
 * And this is the code on line 402-405 in my plugin.php:
    do {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’]));
 * Has anybody an idea? Thank you!!
 * Thomas

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Eleven theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.

 * Hi esmi,
 * resetting the plugins folder via ftp was a good idea. Now I know, that it has
   nothing to do with my theme or the functions.php.
    Thank you!
 * best regards
    Thomas
