Suppress warnings in mediawiki

Question

Is there any way to suppress deprication warnings in mediawiki? For e.g. I am getting this message at the top of some of the pages on my personal wiki site.

Deprecated: Use of MWNamespace::getSubject was deprecated in MediaWiki 1.34. [Called from Scribunto_LuaSiteLibrary::register in /var/www/html/w/extensions/Scribunto/includes/engines/LuaCommon/SiteLibrary.php at line 58] in /var/www/html/w/includes/debug/MWDebug.php on line 375

You can see an example here...

I am not sure if this is php issue or mediawiki problem.

Answer 1

At the bottom of LocalSettings.php:

$wgShowDebug = false;
$wgDevelopmentWarnings = false;

If you want to keep debug messages around, just not the deprecation ones:

$wgDeprecationReleaseLimit = '1.0';

Also, upgrading MediaWiki and extensions helps with problems sometimes😃
