Site WP admin don't open any longer when clicking icon since last update

Since the last update I can no longer click the icon to pen the wp admin page. It just opens the site website instead.

Hi Andrew,

Does it fail for all sites or just one/few?
Can you confirm that MainWP Dashboard and Child are on the latest version?
Which security plugins do you use on your Child site?
