Login Not Working – Nothing Happens After "Login"

Hello guys,

For some reason, I am not able to login to the wordpress site.

When I click to login, the data is erased and nothing happens. If I enter wrong user and password, there ir no error. It literally just resets the login form.

I tried changing the plugin directory name, but issue still there.

Also, I use ManageWp and I am able to login from there.

Any ideas what could be going on?
