The password field is empty message in Chrome

I’m having a problem when trying to log into my Multisite after creating it as a Multisite, but only in Chrome.

When I first try to load in, the login p[age seems to refresh, then clicking to login a second time gives the following error message:

The password field is empty

I’ve cleared the cache, restarted the browser and also rebooted, but still get the error.

It logs me in without a problem in Firefox though.
