Login screen message not showing

Sorry, I don’t understand your issue
Can you explain what you wanted to do and which part fails ?

Please see this screenshot for explantion https://prnt.sc/u1oc1s

This Default Login Screen message does ot appear when customr is redirected to login page. Also as you can see there is an option to add my own custom message which is not saving and does not show either. Hope you can help. Cheers!

what theme are you using ?
is it some common theme or custom made ?

I am using Flatsome with latest Version: 3.12.2

can you also post me screenshot of that login page, where you are redirected ?

Here is the screenshot of Login page https://prnt.sc/u3n593

That login screen is not a default WP login screen, sorry.
Seems like it’s already overwritten by theme functions, so the plugin doesn’t guarantee login screen message will appear there.
It works on default login screens only which are usually looks like this:

and its customised (not overwritte) versions
