Description Dan Barrett 2007-08-02 19:36:22 UTC
Special:Version displays this PHP warning:

Notice: Undefined offset: 1 in <path>\includes\SpecialVersion.php on line 257

This is the arrayToString() line:
  return "($class, {$list[1]})";

Comment 2 Rob Church 2007-08-03 18:25:56 UTC
This looks like it might have been fixed in trunk. Chances are, this is due to a bad assumption about what constituted a valid hook callback "then" vs. "now"; without knowing what extensions are installed (thus, what's being set in hooks), I can't check this too well.
Comment 3 Dan Barrett 2007-08-03 19:11:27 UTC
This was caused by a custom extension we installed, which has the line:

$wgHooks['EditFormPreloadText'][] = array('name_of_function');

which causes Special:Version to display this hook's subscribers as:

(,)
Comment 4 Brion Vibber 2007-08-08 17:31:48 UTC
You've got an invalid hook bit there.

Set:

$wgHooks['EditFormPreloadText'][] = 'name_of_function';
