How to edit with markdown syntax in WYSIWYG mode?

XWiki 10.11.11
CKEditor Integration 1.41
Markdown Syntax 1.2

I can see markdown is listed in editor:

But when I select “Plain 1.0” or “Markdown 1.2”, the page will refresh automatically, and keep in “XWiki 2.1”.

From here, somebody said " Markdown Syntax extension works with WYSIWYG ".

What can I do to fix it?

Hi. It should work out of the box normally. However note that we don’t support old versions of xwiki, see https://www.xwiki.org/xwiki/bin/view/Main/Support. The LTS is 11.10.4.

Could you please upgrade and try again on 11.10.4 or 12:2 and let us know if you still have the problem? You could also try on a clean new version to see if you can reproduce. If you do then it’s a bug and we’ll fix it!

Also make sure you use the latest version of the markdown syntax 1.2 extension. You didn’t mention which version you were using.

Thanks
