Custom Post type will not use special template in Wordpress 3.9.1

[Scott Wright]

Using MF 2.2.2.1 and Wordpress 3.9.1.

I had everything working in WP 3.8.x.

I upgraded and now my custom post type, when displaying a single post, uses index.php instead of single-{post type}.php.

This is in a custom theme which I began in WP 3.6.x. It is pretty empty, just some css and templates.

I have custom page templates that still work.

I copied my template to single-post.php - no luck

I copied it to test_template.php and added a template declaration at the top. I then changed a couple of custom posts to specifically use this template. Still got the index.php template.

I then took EVERYTHING out of test_template.php except a static h1 tag, just to make sure my code in the template was not causing an issue - still used index.php.

My error log is clean.

Any ideas?

Thanks.

BTW - I posted this to wordpress.stackexchange.com, there is a bounty there, http://wordpress.stackexchange.com/questions/145289/wordpress-3-9-not-using-custom-template

After installing debug bar, I notice the following error:

Notice: Trying to get property of non-object in /vHosts/wordpress.salonsuites/wp-content/plugins/magic-fields-2/mf_front_end.php on line 15

not sure if this is part of the problem or not.
