Login issue

ACF Translation Warning: _load_textdomain_just_in_time() called too early for ‘acf’ domain

I was trying to login to my website and it is showing me the error:

There has been a critical error on this website. Please check your site admin email inbox for instructions. If you continue to have problems, please try the support forums.

I used few plugins i.e. ACF pro, wps hide login, wp rocket, etc. I’ve changed the login url something like http://www.example/backpanel. It was fine 2 days back but suddenly stopped working. I’ve tried disable all plugin by renaming the plugins folder, renamed the current theme, removing the cache folder and replaced core files and folders i.e. wp-admin, wp-includes and other root files with latest. When I change the theme to any default theme and try to login it shows me above error. On custom theme it shows the notice:

Notice: Function _load_textdomain_just_in_time was called incorrectly. 
Translation loading for the 'acf' domain was triggered too early. 
This is usually an indicator for some code in the plugin or theme running too early. 
Translations should be loaded at the init action or later.
