I took a look; apart from the fact that these are posts from 2021 but then the problem doesn't change, but everything remains as before; if you think it doesn't affect the SEO of the portal it doesn't matter but if it can compromise the results on search engines, obviously a decision must be made.
And I would like to add, I have other sites with joomla where helix is used and similar problems have never occurred, that's why I associated the mix-up with the gazette template; just tell me if you think it can affect the general SEO aspect, then I'll decide; thanks, Stefano
