Deprecated Message on Mediawiki 1.4 with latest Version

[Domoel]

I get the following error when using the extension on Mediawiki 1.40.

Could somebody explain to me how to fix it?

Edit:

My LocalSettings.php does contain the following config for the extension:

LinkTitles Settings

$wgLinkTitlesParseOnEdit = true;
$wgLinkTitlesParseOnRender = true;
$wgLinkTitlesSpecialPageReloadAfter = 1;

When I disable these settings the error disappears. Do I have to change something here?

A couple of deprecation warnings have crept up with the last several releases of MediaWiki. Hopefully I can look into it soon.

In the meantime, you can disable the warnings by changing your LocalSettings.php

$wgShowDebug = false;
$wgDevelopmentWarnings = false;

Alternatively:

$wgDeprecationReleaseLimit = '1.0';

You don't need to change the LinkTitles settings.
