Topic on Extension talk:DonateBoxInSidebar

@WikiForMen: Could you please elaborate on why you added {{incompatible}} to this page? An extension that's truly incompatible with 1.37 or later should be considered for archival soon, but that's not really fair without an explanation of the problem.

All mentioned extentions use hook SkinBuildSidebar to inject HTML into the sidebar.

"As of MediaWiki 1.39, injecting HTML is no longer supported with this hook. If you are looking to inject HTML, such as to put an ad in the sidebar, you must use Manual:Hooks/SkinAfterPortlet or similar."

So mentioned extentions have to be rewritten to support actual versions of mediawiki.

In that case the version parameter should be 1.39 not 1.37, right? I've changed it to 1.39.

Yes. I was confused with the version number because the reported issue with skin Timeless was regarding 1.37.

Ditto with Extension:SidebarDonateBox - it's preferable to explain what the specific issue(s) are so they can be addressed.
