Excluded by ‘noindex’ tag
Some DokuWiki pages are tagged with the
noindextag. This is intentional, the warning can be ignored. Maybe you can disable this check in the Google settings?
Alternative page with proper canonical tag
How Google comes up with the idea of issuing a warning message in this case is a mystery to me.
The best way is to check yourself via Google search results whether those pages are indexed that should be found. If everything is ok there, there is no need for action.
