When I try to run maintenance/runJobs.php, I'm getting the following error:
PHP Notice: Undefined variable: type in /var/www/eamon.wiki/public_html/mediawiki-1.30.0/extensions/HeadScript/HeadScript.php on line 3
I'm on MediaWiki 1.30.0 and have the latest HeadScript extension installed. Any idea what might be causing this problem? Huwmanbeing (talk) 18:04, 22 January 2018 (UTC)
HeadScript.php uses a (deprecated) array that adds the extension's information to the wiki's Special:Version page.
To fix the PHP error, in /path/to/mediawiki/extensions/HeadScript/HeadScript.php, change the following line (line 3):
$wgExtensionCredits[$type][] = array(
to
$wgExtensionCredits['specialpage'][] = array(
The developer simply forgot to replace $type with the proper value.
For a complete explanation of $wgExtensionCredits, see Manual:$wgExtensionCredits.
That solved it for me too! I'm going to try and submit a change in the github repository.
