Topic on Project:Support desk/Flow

Is there any reason that the following line of code in an extension would give me a 500 error?

$contentRenderer = MediaWikiServices::getInstance()->getContentRenderer();

I wonder whether it's my MW version (1.35.8) or maybe something else about how things are set up on my wiki.

Further details at Extension_talk:Cargo#RSS:_Does_"feed"_export_display_format_work_with_MW1.35?.

Thanks.

Hi!

Yes, this code is only available since MediaWiki 1.38. See https://github.com/wikimedia/mediawiki/blob/c16fae21f5225a188cb0d89da8db26f1549a8df5/includes/MediaWikiServices.php#L973-L979

You will either need to download a version of Extension:Cargo that is compatible to MediaWiki 1.35, or upgrade to the latest MediaWiki LTS version 1.39.

Thank you for the helpful reply. I plan to upgrade soon. Another option might be to persuade the extension authors to provide a fallback option for older wiki versions. Your information might help with that :-)
