jos-Error: COM_CONTENT_ERROR_ARTICLE_NOT_FOUND

Hi,
I use Community Builder 2.2.1+build.2018.10.16.19.32.44.38e6b06fc with Joomla 3.8.13. Everything works quite fine except my registration page. I set up a menu item with the type Community Builder -> registration form but when I click on it in my frontend, I get an unstyled page with an error: jos-Error: COM_CONTENT_ERROR_ARTICLE_NOT_FOUND
Any idea, what could be wrong here?
Regards
Markus

Looks like that's an error Joomla throws when trying to access a Joomla article that doesn't exist. No idea why registration would be throwing that. Are you sure your Joomla menu item is correct? Try navigating to the below directly (add it after your domain).

index.php?option=com_comprofiler&view=registers

Hello Kyle,
thank you for your reply. I have solved the problem now. It was connected to the multilingual setup of the site: It seems, the home menu item of one language was the first, initial home menu item of the site and the dummy menu item for all languages that is required for Joomla was a new one. I swapped them and now it works. I didn't realize, that I must use exactly this home menu item as a dummy home for all languages...

I did solve the problem for a few minutes, but now I have exactly the same problem again: The problem must be connected to the three home links I have with two languages. When I disable the language plugins and remove the home link that is associated with all languages, the cb registration works fine.

For a multilingual setup you typically will need a menu item for each language or have a menu item that's set to all languages. Not sure how it'll behave with a menu item for one language then a second menu item for all languages.

according to the documentation on joomla.org, for two languages three menus are required: docs.joomla.org/J3.x:Setup_a_Multilingual_Site/Creating_menus (bottom of the page), or am I missing anything here?
