i have multisite wordpress (version 5.7.2) with wordfence plugins installed. after several days not logged in i found email notification from wordfence reported that people try login using admin account but unsuccessful.
i try to login by myself too and unsuccessful. so i rename wordfence plugin folder to disable it.
i successfully logged in using admin account from subsite (sub.mainsite.com) but not from main site (mainsite.com). and i cannot access network admin menu in mainsite.
my question is, how to be able to re-access main site using admin account?
