About that “Weekly jQuery Migrate Status Update” email

With the update to WordPress 5.5, a migration tool known as jquery-migrate was disabled by default. This disabling of that function may lead to lacking functionality or unexpected behavior in some themes or plugins that run older code.

The word “deprecated” simply means that some function within a plugin or theme no longer meets the latest WordPress coding standards.

WordPress is evolving and in doing so, some older coding standards will be left behind, to be replaced by newer faster, more secure standards. If you have received a deprecated message, like the one below, the message is simply a reminder that older code may stop functioning someday in the future.

Since maintaining the latest updates is just smart business where WordPress is concerned, be sure to check what is described as deprecated within the email alert and update that if possible.

In the example notice above, you’ll see that the alert relates to the “Dandelion” theme. Once the client updated his theme the error reports ended—the Enable jQuery Migrate Helper plugin was no longer required and then deleted.

If you wish to stop your website from sending these messages you could try deleting the Enable jQuery Migrate Helper plugin. If your website functions without the plugin, you should be fine for a while.

If your website appears broken after disabling the plugin, just add the Enable jQuery Migrate Helper plugin back to fix the issue.
