Multiple Use Issues – Please Help

I’ve encountered multiple issues trying to get this to work properly. I initially started a thread related to one, but closed it and decided to outline them all in one.

Sermons listed here: https://www.fbcfloralcity.org/sermons
Plugin version: 1.7.4
WP Version: 3.6.1

Issue #1: Error 404 Trying to See Series

The audio sermons display fine, but when I click on the series title (e.g., “Sermon on the Mount”) all I get is “Error 404.” Under the plugin settings I’ve got the following information:

– Archive Page Title: “Sermon Archive”
– Archive Page Slug: “sermon-archive”
– Common Base Slug: checkmarked (I get error 404 with this checked or not)

Issue #2: Can’t Use Pre-Existing “Sermons” Page

I had created a ‘blank’ page called “Sermons” with the the slug “sermons” for an older version (pre-plugin), so I added the shortcode [sermons] on that page.

When I change the Archive Page Title and Page Slug to “Sermons” and “sermons” respectively, going to the URL shown above displays a single sermon with the featured image as both the feat. image and the sermon title. I don’t want to use “sermon archives” but just simply “sermons.” I can’t get that to work.

Issue #3: Duplicating Individual Sermon

When I go to view the individual sermon, it shows the sermon twice on the page. I saw something like this in a one year old post, but it said that the plugin was updated to resolve it. But I’m getting it. What could be causing this?

So far this plugin is quite the headache, though I’m hoping to get it to work properly.
