So, I was carefully following the Wordpress Codex to create a Custom options panel for a custom post type.() Specifically, Example 2.
Everything was actually working well with the post types and the options panel. However, when I later went to the Media Library it wouldn't load. I tried signing out of the admin area but when I tried to sign back in and it wouldn't load. I had to manually remove the plugin from the directory to get back in.
I uploaded an older version of the plugin that did not have the options panel and working fine again.
I thought I would try going line by line to see what the bug was and it seems that as soon as I declare the class, it crashes the admin area and I have to delete it and start over.
I have been scouring the forums and can't figure it out. I have created custom post type plugins in the past but haven't added this options page before so I am really stuck.
CUSTOM POST TYPE PLUGIN CODE: EDIT: (I BROKE UP THE CODE INTO TWO SECTIONS TO MAKE IT A BIT EASIER. THIS IS THE WORKING CODE THAT FOR CREATING THE POST TYPES)
