I've been a software engineer for 30 years, but am fairly new to WordPress, so please forgive me if I stumble around a bit.
I've created a custom post type, Press, with several custom fields. I used the Press menu on the admin panel to create a few posts of the new post type, and the form appears to save correctly. However, when I click 'View Post' from the edit form (after publishing) I get a 404. Also, when I look at all posts of type Press in the admin panel, no posts show up in the list. At the top of the screen where I can select by status, it says 'All (4) | Published (3) | Draft (1)' so it seems to know that I've created 4 posts of this post type. But in the list it says 'No press found'. See screenshot here.
FYI, I did create a single-press.php template in my theme using the template code provided by the plugin, but it 404's without loading the template.
Don't know if it helps, but my site is at ss.jbchristy.com. It requires http authentication while under development. You can use username guest / password welcome for a little while.
Thanks in advance for your help!
