Possible - could you zip up a copy of that vars file and PM it to me? (I can't find a banilas.vars in your Members folder and without looking at that file you're asking me to blindly guess the cause of the problem.)

works, there may be a problem with the permanent ban as it affects this-remember I had a problem that was banned forever for login-banilas for the period from January 1, 1970 to the expiry date in a year from the bizarre-we corrected, but maybe this affects how this situation?

I cannot reproduce the issue on a different forum even with a banned member although I am still looking into it.
I made an edit to your Profile.pm - please see if that solves the problem.

But I suspect the problem is with that member's vars file.

corrections did not help, I explain the essence of the error and the problem is the fact that this behavior and such a reaction only to the nickname I pulled from the permanent ban-with the rest all right

not worked

This is no doubt the same date-time issue as before.

In Admin/Settings_Main.pm find

if (
     eval {
         require DateTime;
         require DateTime::TimeZone;
     }
   )
 {
     DateTime->import();
     DateTime::TimeZone->import();
     load_language('Countries');
  

and replace with

if (
     eval {
         require DateTime;
         require DateTime::TimeZone;
         require Locale::Country;
     }
   )
 {
     DateTime->import();
     DateTime::TimeZone->import();
     Locale::Country->import();
     %countrytime_txt = ();
     my @newmycntry      = DateTime::TimeZone->countries();
     foreach my $country_code (@newmycntry) {
         my @local = DateTime::TimeZone->names_in_country($country_code);
         my $country = code2country($country_code) || uc $country_code;
         if ( $country eq 'UK' ) { $country = 'Great Britain'; }
