On the Member Management screen where it shows members to be approved/declined/etc., text display is garbled. See the attached screenshot. This is on Chrome. Edge also shows garbled. Firefox doesn't. Thanks.
It looks like you don't have the correct files in place for the control panel, because you should see a white and blue UI. From your v7.6.0 install archive please make sure that you're using the same files in the /styles/admin.css, /admin, /languages/english/admin, and the /templates/admin folders.
Edit: Looks like it might just be the missing /admin.css file, but just wanted to make sure you updated the others if you left them out for some reason.
