What does this mean(.htaccess)?
 

Hallo,

What to do, when this error shows:
.htaccess password protection is required to access this script.
See the .htaccess section of the software manual for assistance with this error.

--------------------------------------
Domain parameters:
CGI:on
PHP:on
--------------------------------------
.htaccess:
AuthType Basic
AuthName "directory"
AuthUserFile /var/www/mydomain/data/www/mydomain/cgi-bin/admin/.htpasswd
<Limit GET POST>
require valid-users
</Limit>
--------------------------------------
.htpasswd:
admin:suhhh
--------------------------------------

It's mean you need to set up restricted access for this directory. You can do it with ISPmanager, "World Wide Web" - "Directory access".
