I see what you’re referring to. I haven’t updated the header.php and have looked at all the files containing ‘wp_admin’. I did early on download the custom demo files and saw in one of the XML files
.., but I now deleted that file and the extra still remains.
With the new version of the theme, I only uploaded header.php in case somehow that was the problem, but that didn’t resolve the issue. I also deactivated each plugin, deleting others that I no longer needed.
When selecting the child theme editor, I only have the functions.php and styles.css available.
