[1] opac-registration-verify.pl forbidden pattern: Script permissions is authnotrequired => 1, it is correct for an OPAC script, not intranet (bug 24663)
    => Do not go back to authrequired => 1. Use a check on OpacPublic.
[2] opac-registration-invalid.tt missing_filter at line 41 (<p>Error [% error_type %]: [% error_info %]</p>)
[3] opac-memberentry.tt missing_filter at line 131 (<p>Error [% error_type %]: [% error_info %]</p>)
