404 Errors non existent pages since I installed Newspaper theme

I installed Newspaper theme, and since then I’ve been getting a lot of 404 errors linking to non existent pages. It seems somenthing is trying to get to pages with almost the same link as my news posts, like:

/2017/09/17/trilha-cervejaria-novidade-em-perdizes/contacts/
/2017/09/17/trilha-cervejaria-novidade-em-perdizes/en-us/contact-us.html
/2017/09/17/trilha-cervejaria-novidade-em-perdizes/p/fale-comigo.html
/2017/09/17/trilha-cervejaria-novidade-em-perdizes/uk/en/corporate/company/contact/

my post link is /2017/09/17/trilha-cervejaria-novidade-em-perdizes/

Do you know what might be happening?!

I don’t think that’s the problem. I’ve been reading about it and they say it’s a theme problem. I misinstalled the theme with sample pages and posts and then I deleted everything. It seems the problem is with that. What can I do?!

I’m getting the errors on Redirect Plugin. It says it’s coming from the site.

Theme would only have those pages there if
a) you’ve imported demo page content
b) you’re using translation plugin to build alternate page versions

Ideally clear all caching, remove all demo content, resave permalinks, clear all transients with wp-optimize; check you htaccess for old redirects — in case you have old redirects going someplace for stuff not actually there.

Force resave your sitemap; resubmit to Google etc.

Pages removed will stop getting pinged eventually. Hurts nothing to get some 404s for temporary pages. Nobody on the web should be linking to temp pages so zero issues for site other than getting temp errors like that.

Not sure that helps – but common issue when you have temp pages, then delete, then have redirects created for non existant pages to near matches; esp if the auto-redirect plugin links to pages you then delete also. Get a bad redirect ‘chain’ going there.

Food for thought.

Thank you very much for your help. Still trying to figure out what’s happening here.
