I've been scouring the forums and tried a bunch of things with no luck.
At least before the upgrades (WordPress core and this plugin), filling out the custom text area field generated
<p> tags as appropriate; however, it stopped working completely.
When going to old custom posts and viewing the HTML view of the add/edit post form, paragraph tags are seen.
I found a bunch of posts including suggestions to apply filters to the template, which I haven't had luck with.
The template just calls the_content().
Any help/suggestions would be greatly appreciated. Thanks.
