    Hi. I recently updated all my plugins. Following that I updated to the latest version of WordPress (7.1). After the update I am unable to login and I receive the message below. I have replaced my wp-admin and wp-includes folders and I have disabled all of my plugins, but I still receive the following message.

    Any help on getting the site back up is greatly appreciated. I have access to Plesk and PHPMyAdmin.

    Thank you!

  • Hi @dtnorz81

    The _wp_register_default_icon_collections seems a recent addition to WordPress:

    https://core.trac.wordpress.org/changeset/62748

    I suggest trying to reinstall the WordPress core as first step https://wordpress.org/support/topic/reinstall-wp-from-dashboard/#post-18089828

    Thanks Patrick – I appreciate the reply. I was able to revert back to WordPress 7.04 and all is well. I guess I will wait a few months for the bugs to be worked out on the 7.1 build.

    To me, it sounds more like you’re using a plugin that’s trying to use this new feature in WordPress 7.1 – but incorrectly. I’d recommend checking to see which one it might be. You can also deactivate all plugins, update to WordPress 7.1, and then reactivate the plugins one by one. As soon as the error reappears, you’ll have found the culprit plugin. I’ve already successfully used this new feature myself.
