Watchdog: Notice: Undefined variable: node in autotagging_ajax() (line 55 of /home/hoslot5/public_html/sites/all/modules/autotag

I got that one here;

http://EXAMPLE.ORG/ajax/autotagging
REFERRER http://EXAMPLE.ORG/node/2522/edit?destination=admin/content/node

But also here:

Notice: Undefined variable: node in autotagging_ajax() (line 43 of /DRUPAL7/sites/all/modules/contrib/autotagging/autotagging.module).
Notice: Undefined variable: node in autotagging_ajax() (line 37 of /DRUPAL7/sites/all/modules/contrib/autotagging/autotagging.module).

you have to remove the two last arguments of module_invoke_all

so - form

module_invoke_all($hook, $node, $text);

to

module_invoke_all($hook);
