Dashboard error: register_uninstall_hook was called incorrectly

It’s a “Notice” that appears both in the Dashboard and prints to the top of the page on the frontend. The HTML looks like this:

<br />
<b>Notice</b>:  register_uninstall_hook was called <strong>incorrectly</strong>. Only a static class method or function can be used in an uninstall hook. Please see <a href="https://codex.ww.wp.xz.cn/Debugging_in_WordPress">Debugging in WordPress</a> for more information. (This message was added in version 3.1.0.) in <b>/srv/www/mysite/htdocs/wp-includes/functions.php</b> on line <b>4147</b><br />

This is in local development with the following wp-config.php settings:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', true );
define( 'WP_DEBUG_LOG', true );
define( 'SCRIPT_DEBUG', true );

I haven’t yet updated in production and I’m not displaying Notices live so a URL to the website wouldn’t help.

This Notice does not affect the display or functionality of the AddThis plugin and sharing buttons.

Here’s a screenshot of the Notice that appears at the top of a blog post page: https://s3-us-west-1.amazonaws.com/redbridgenet/addthis-notice-screenshot.png

Thanks Leland.

I’ll let you guys mark as resolved once the fix is out?

Leland, just downloaded the latest update and I can confirm that the Notice no longer appears.
