After upgrading XWiki from 7.3 to 15.0.12 the navigation panel is not displayed. When I click on the Admin users profile I see the following error:

There are several error messages in the log:

Seems that the parser for the old wiki format is missing.
Do I have to install it (how), because the new version doesn’t install it by default?

It seems you’re still using a syntax that has been deprecated for over 15 years :slight_smile: (xwiki/1.0)

If you really want to continue using it (not recommended), you’ll need to install a contrib extension to support it: https://extensions.xwiki.org/xwiki/bin/view/Extension/XWiki%20Rendering%20-%20Syntax%20-%20XWiki%201.0

Note: I have no idea if that extension still works

The recommendation is to convert your pages from xwiki/1.0 syntax to xwiki/2.1 syntax

basically yes

Thank you for the quick answer!

How can I convert the pages?

Either manually of you can try to install the extension and then edit the page and then for each page, edit it and select the “XWiki Syntax 2.1” → https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/PageEditing#HConvertingbetweenSyntaxes

We still see errors concerning the missing XWiki 1.0 Parser in the log file.
Is there a way for listing all Wiki pages stored with the old XWiki 1.0 syntax -
in the admin UI or via an SQL statement?

The Macro works perfectly. Thanks a lot!
