For anyone who’s still seeing this problem, I have a fix available for it available on our site.
There’s a patch file available here: https://www.askyourpreacher.org/wp-bible.patch
If you’d rather have the already-zipped version, you can use this file: https://www.askyourpreacher.org/wp-bible.zip
The plugin’s also been modified to handle references with a period after the book abbreviation, such as 1 Cor. 1:2.
@tituslowly: That’s actually a custom theme we designed just for our site. We’ve got someone who came up with a pretty design, and then we heavily modified the default Kubrick theme to look like the design she came up with.
