My Account - /index.php/my-account?layout=edit in VM 4.4.4

[Slavomir]

Hello
My Account - /index.php/my-account?layout=edit no longer works after upgrading VirtueMart from 4.4.0 to 4.4.4. Users can no longer register. The page just reloads after the user fills out the form and clicks the save button. The same happens when existing users try to edit their information and save. I had to downgrade VirtueMart back to 4.4.0. Then the form works again. Is this a bug in VirtueMart 4.4.4?

Found what was wrong.

VM 4.4.4
Line 236 if(/*$currentUser->guest!=1 or !$cartObj or */ ($currentUser->guest==1 and $register) ){

Removed comments /*......*/. Users can register again.

Got also following warning with VM 4.4.4. How can I fix this?
