I created a new tag (in my user profile). I clicked on the link and the tag page displayed ok. I clicked on "Edit this tag" and got: Warning: array_shift() [function.array-shift]: The argument should be an array in /moodle/19/tag/edit.php on line 18 Notice: Trying to get property of non-object in /moodle/19/tag/edit.php on line 32 Notice: Undefined property: stdClass::$description in /moodle/19/tag/edit.php on line 40 Notice: Undefined property: stdClass::$descriptionformat in /moodle/19/tag/edit.php on line 40
