i can’t go to the “boutique/admin” else it say “403 Forbidden
The website’s configuration prevents you from accessing this page.”
In the boutique/admin folder is a .htaccess file which says “deny from all”. It looks like it’s supposed to be used to whitelist access to specific IP addresses only.
You could whitelist your own IP address by adding a line like allow from 126.96.36.199 to the file (where 188.8.131.52 is your IP address) or remove the file to allow anyone to access the admin pages (depending on whether there is an additional authentication system).
