Doesn’t matter if PHP 8.0, 8.1 or 8.2 they all have the warning. Nt problems using 7.4 but it is not supported and we need to update but don’t really want errorlog files growing quickly. I there any simple way to track down the cause? * [msemler](https://wordpress.org/support/users/msemler/) * (@msemler) * [2 years, 4 months ago](https://wordpress.org/support/topic/warning-undefined-array-key-23/#post-17333329) * This is still a problem and not resolved [@elementor](https://wordpress.org/support/users/elementor/) * [CMJ](https://wordpress.org/support/users/cmj/) * (@cmj) * [2 years, 3 months ago](https://wordpress.org/support/topic/warning-undefined-array-key-23/#post-17403160) * Same problem here, but it was fine last night. Woke up this morning and unable to access site front end or admin. Tried deactivating plugins, tried downgrading PHP, but didn’t help. Error log shows the same error as original poster.
