Title: Undefined array key Last modified: May 14, 2025 --- # Undefined array key * Resolved [Beee](https://wordpress.org/support/users/beee/) * (@beee) * [1 year ago](https://wordpress.org/support/topic/undefined-array-key-62/) * Can I include an acf field, which is connected to a post, while excluding posts( to which the field is connected) ? * I have checked acf fields and added the key to it. I then excluded posts and got the following notices/warnings. * `PHP Warning: Undefined array key "cn_links_to" in /var/www/html/web/app/plugins/ broken-link-checker/legacy/modules/containers/acf_field.php on line 522` * This comes after I entered the ACF field key for the field cn_links_to. * I only check for broken links in pages, blogroll, nav items and a custom post type, but not in posts, where the field cn_links_to is used. I don’t care about the content, because that’s not used. Oh and I use the local version, not the cloud.

The Local Engine also provides an option to disable ACF fields from scan, you can find the same under the “Look for links in” tab. * PHP warnings generally shouldn’t cause any issues to the functionality of the plugin. However, could you please provide more clarification on how you have configured the exclusion, which resulted in the mentioned PHP warning? Please share a screenshot of the same so that we can better understand and check this further. * Best Regards, Nebu John * Thread Starter [Beee](https://wordpress.org/support/users/beee/) * (@beee) * [1 year ago](https://wordpress.org/support/topic/undefined-array-key-62/#post-18466854) * [@wpmudevsupport14](https://wordpress.org/support/users/wpmudevsupport14/) thanks for the reply. * I have to correct you a bit. I didn’t EXCLUDE any acf fields, I included them and excluded the post type posts. * I know warnings don’t cause an issue, but they clutter up my logs, making it harder to identify more serious issues. * I posted this before the most recent update was released. After re-testing it, I haven’t seen any warnings in logs again, so maybe there was a fix in there as well (unknowingly). * On another note, I checked the warnings screen. There was a message/link, which said “Change warning settings” and links to /wp-admin/admin.php?page=link-checker- settings#blc_warning_settings where it says, “Sorry, you are not allowed to access this page.” * Plugin Support [Imran – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support9/) * (@wpmudev-support9) * [1 year ago](https://wordpress.org/support/topic/undefined-array-key-62/#post-18467021) * Hello [@beee](https://wordpress.org/support/users/beee/), * I hope things are going well for you. * I am glad the warning issue was resolved after the recent update. * > On another note, I checked the warnings screen.

However, I couldn’t get this to my system’s PHP error, access, crons, and BLC logs either. * Can you share more clarification on where you got this? So we can check and report to the devs. * We look forward to hearing from you soon. * – Kind Regards, Imran Khan * Thread Starter [Beee](https://wordpress.org/support/users/beee/) * (@beee) * [1 year ago](https://wordpress.org/support/topic/undefined-array-key-62/#post-18467171) * I am not saying it’s 100% resolved yet, only there are no more warnings yet. * I nuked the check and have to wait if the correct links show up in the checker. * Regarding the warning, if I click the admin filter warnings, it shows up.
