I am having a strange issue. I have made a custom post type that only supports having a title. I then used metabox AIO to create some custom fields.
The issue is that even after saving/publishing a new post, when I try and click away my browser warns me that there may be unsaved changes. This happens in Firefox and Chrome but not Safari.
Is there any way to get rid of these annoying popups? I have tried creating a new post type using MB Builder to verify that it is not my code, and the problem happens then too.
