Disqus comments box/ads still visible on website even though plugin deactivated

Hi there,

Due to the addition of ads to the Disqus comments section, I want to remove Disqus from my website.

My first problem arose trying to manually sync comments (even keeping the timeframe to 1 month’s worth of comments at a time, would make the sync hang).

I’ve looked up info about this, and maybe it is a REST API issue.

That aside, I just want the Disqus comments section to no longer be displayed on my website.

I have deactivated the plugin, and when I view a post with a comment on it whilst I’m logged as admin, I will see no comment, but the native WP comments box (settings = can only comment when logged into an account).

However, if I view the same page whilst logged out (or incognito) the Disqus comments box and ads (and comment) are visible.

How is this possible if I have deactivated the Disqus plugin? Does it need to be deleted entirely?

Any help would be great, thank you!
