Problem with the Creole Plugin in the Dokuwiki 20101107 “Anteater” release

Posted by ts in Computing on 12 November 2010

When the upgrade occurred, a bunch of errors, such as:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'Doku_Renderer_metadata::section_edit' was given in /home/bilye3/public_html/dokuwikiStandard/inc/parserutils.php on line 419

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'Doku_Renderer_xhtml::section_edit' was given in /home/bilye3/public_html/dokuwikiStandard/inc/parserutils.php on line 555

would appear at the top of each page (sometimes multiple times).

After quite a bit of searching, the answer appears to be:

Comment out lines lines 67 – 72 of lib/plugins/creole/syntax/header.php (within the given dokuwiki installation), as follows:

if ($level <= $conf['maxseclevel']) { // $handler->_addCall('section_edit', array(
// $handler->status['section_edit_start'],
// $pos-1,
// $handler->status['section_edit_level'],
// $handler->status['section_edit_title']
// ), $pos);
$handler->status['section_edit_start'] = $pos;
$handler->status['section_edit_level'] = $level;
$handler->status['section_edit_title'] = $title;
}

Make sure you then

touch /conf/local.php

(within the given dokuwiki installation)
and the problem should be resolved.

This fix was provided here:
http://www.dokuwiki.org/plugin:creole
(see the bottom of the page)
and the cache touch issue was referenced here:
http://forum.dokuwiki.org/thread/6009
(once again, at the bottom of the page).

Here is a copy of the modified header.php for reference purposes:
