PHP Warning: Undefined array key “type”

Hello @robdasailorgmailcom

Thanks for reporting this error and providing the log information! That PHP warning is definitely something we need to look into, especially since it’s interfering with your Block Editor (Gutenberg) experience.

The specific warning:

PHP Warning: Undefined array key “type” in /wordpress/plugins/amp/2.5.5/includes/validation/class-amp-validation-manager.php on line 1317

…is coming from the AMP plugin (version 2.5.5). It indicates that the validation manager is trying to access an array element with the key “type”, but that key doesn’t exist at that point, causing the warning. While this is technically a warning and not a fatal error, PHP warnings can sometimes break page execution or, in this case, prevent the editor from loading correctly, especially within a highly validated environment like AMP.

Since you are using a simple WordPress.com install, and everything is up-to-date. This likely points to an incompatibility or a bug triggered by a specific piece of content or configuration on your site.

Can you please share the link for the post where you are getting the warning? So we can debug this further.
