Joomla! 4 - 404 Not Found - Router.php (153) and ArticleModel.php (222) errors Topic is solved

[strudel]

After upgrading to Joomla! 4, when I try to access my articles via the menus or an article-lister module, I get a lot of 404 Not Found errors, referencing the following php files:

/home/username/public_html/libraries/src/Router/Router.php (153)

/home/username/public_html/components/com_content/src/Model/ArticleModel.php (222)

Doe anyone have any idea what's wrong?

Check the URL of the menu entry and the article it is referring to. Does the article exist? Show us an example, or, even better, give us the URL of the website and links to the pages with the 404 errors.

I'm not sure yet but I think I might have found the root cause of this and a couple other issues I have been experiencing. I posted it as a separate topic here:
