Hello,
About a month ago, I created a clean standard post page. I set the permalink in WordPress’ editor to x/blog/ and everything worked for a month. I used All In One SEO at the time and continued to develop the page.
I switched to Yoast SEO today. I don’t know if this change caused a problem with the /blog/ slug, but I noticed that now, when I access x/blog/, I land on a “post archive” page that I don’t want.
– I didn’t change permalink settings
– I didn’t change page settings for this blog page
– No changes to robots.txt that would block this
