error in Joomla 5____ Invalid field: Created By

Hi Alberto,

Thanks for reaching out. The “Invalid field: Created By” error in Joomla 5 usually occurs due to user permissions or missing user data. Here are a few steps to troubleshoot:

1. Verify the User Exists: If the “Created By” field references a deleted or inactive user, try assigning a valid user.
2. Ensure an Author is Set: If an article has no author set in the publishing settings, this issue can arise. Assigning a valid user in the “Created By” field should resolve it.

If the issue continues, let me know your Joomla version and whether you’re using any custom extensions or overrides.

Best,
