[@send2teresa](https://wordpress.org/support/users/send2teresa/), that is not the same error. The original post was about an “undefined offset”. You’re getting“ undefined variable _POST” on every single variable that was supposed to be posted. That tells me you’ve got something interfering with that form post. Can you try disabling your other plugins to see if the problem goes away? * [send2teresa](https://wordpress.org/support/users/send2teresa/) * (@send2teresa) * [10 years, 3 months ago](https://wordpress.org/support/topic/php-errors-when-i-try-to-save-a-button/#post-7058683) * Good to know.
