There must be some plugin that is causing the issue, you should try disabling all the plugins and reactivating them one by one and see if you find out which plugin (or the theme?) is really causing the issue, if it doesn’t work for you there is always another way.
you can create as many administrator account as you want from phpmyadmin, so here goes the tutorial that i always follow if i ever face some issues regarding the admin accounts,
if you want everything to be proper first delete old admin accounts (don’t worry, posts won’t be deleted) and create new ones.
P.S: never ever give your client the full Administrator access unless they are totally dumb 😀
you do realize what is the reason for that 😉
