I have just upgraded to 4.7.3 and have an issue with my custom post types.
The posts were displaying fine until the upgrade, and I’m not sure how to fix this.
They all now use the index.php file instead of single.php, which isn’t right. My static / list pages all work fine, just the custom posts.
Please help. My PHP isn’t the greatest. I have tried deactivating plugins and it’s still not working.
