Link from blog page to single post page not working

Hi everyone.

We’ve just noticed that when you go to the blog page of our site (https://www.love-yourself-naturally.com/articles/) and click on a post link, it takes you to a page where there is just an excerpt of the post instead of the single post page.

In the “post specifics” area of the settings, we’ve got the blog page set as 3 columns of excerpted posts. And when you click one of the posts, the page looks like the blog page but with just one excerpted post.

We’ve tried changing the number of columns and removing the excerpts, and this fixes the single post page… but also changes the blog page layout.

We have been making a few updates to the site recently, but just with regard to colours, fonts, images, etc. So no idea what’s going on.

Any ideas? All thoughts welcome.

We’re using Weaver II theme with White subtheme.

To answer a question asked in a different forum (when I was told to post here), yes the theme does still have its template file single.php.
