Thread:Project:Support desk/Installing extension on 1.19.1

I start to install few extension to 1.19.1 mediawiki.

In each extension there is a list of mediawiki version that it support. Can I install on 1.19.1 extension that fit to 1.17.x or I must 1.17.+?

The extension I need to install usually marked as obsolete, unmaintained or archived. Probably it's the reason the version is not updated. The extension I need: FCKeditor SimpleSecurity CategorySuggest StubManager CrudeProtection Another problem I have, the extension Group Based Access Control is unstable and unmaintained. It's recommend to download AccessControl but the download tar file is empty.

Thanks.
