404 Errors

Hi there..
Not sure what's happening here - I use Route66 for a number of sites and I don't think this has happened anywhere else:
404 error once URL pattern is established. Pattern is: /{categoryAlias}/{articleAlias}

URL (Links) look correct but produces 404 error (Title, Read more, and from Module). The articles in this category are not linked from menu.

This is latest Route66 and Joomla 5.0.2

Thanks so much,

Yup, plugins are enabled. I sent private ticket - thanks so much.

Huh. Yep, all good now. So bizarre... I have the very same setting on another site on the same server with no issues.
Thanks so much!!!
