As you suggested, I tried re-saved existing post types, and every time I clicked save button, same error message appeared. Thinking about some collapsed data, I deleted all existing post type and taxonomies (I have a backup of whole this site), then try to create a test post type. Error message appeared. Then, I deactivated and deleted this plug-in, reinstall latest version again, then tried to create new test post type. Still it showed error message. I deleted this newly created test post type, and got the debug info. Here is the link: [https://www.dropbox.com/s/tkgdqruv7wzdzhy/20190427_debug.zip?dl=0](https://www.dropbox.com/s/tkgdqruv7wzdzhy/20190427_debug.zip?dl=0) * I wish you can have some solution. * Hiroyuki * Plugin Contributor [Michael Beckwith](https://wordpress.org/support/users/tw2113/) * (@tw2113) * The BenchPresser * [7 years, 1 month ago](https://wordpress.org/support/topic/error-message-755/#post-11474284) * You’re still getting the error even without anything saved for your CPTUI settings? or did they go away once you removed everything? * Beyond that, I don’t have any sort of readymade solution or hotfix available, since it should be saving at LEAST an empty array for the label spots, last I checked. I do strive to avoid warnings/notices whenever possible. * Thread Starter [hkakinuma](https://wordpress.org/support/users/hkakinuma/) * (@hkakinuma) * [7 years, 1 month ago](https://wordpress.org/support/topic/error-message-755/#post-11475844) * Yes, once I clear re-installed CPTUI, error message is disappeared. However, when I tried to create new post type, it appeared again.

I’m legitimately curious if there’s some plugin or piece of code in your site that is affecting the $_POST global before we can get to it.
