I'm seeing this same issue after upgrading to 1.14.0. I was unable to login with my admin password. The loading spinner just keeps spinning, but it seems that the login fails with no reason given; the following response is returned from the login request:

{
    "Action": "AdminLogin",
    "Result": false,
    "Time": 11
}

I tried resetting the password to 12345 as described in #28 but I get the same behavior.

Note that this is different from when I enter an invalid user name or password, in that case login response is as follows, and an error message appears in the UI:

{
    "Action": "AdminLogin",
    "Result": false,
    "ErrorCode": 102,
    "ErrorMessage": "",
    "ErrorMessageAdditional": "",
    "Time": 1015
}

I have the same problem like @jwoldan

After upgrading 1.13.0 to 1.14.0, I can continue to login to the admin panel and it works fine for me.
PHP 5.6.40

Same here... upgraded from 1.13.0 to 1.16.0, wrong password correctly returns an error but correct password leads to spinner forever. Did you find a workaround?

From this source I'd say that the .ini file cannot contain a plaintext password, except if it is the default 12345.
So the solution is to set that back to 12345 then login and change it from the interface.
