Support

I am struggling to understand the issue you're trying to ask help with. If I understand you correctly, you tried using the "Password-protect Administrator" feature of Admin Tools and you believe nothing happens. This feature works by creating a .htaccess and a .htpasswd file in your administrator directory. So, the first thing to do is to check that these two files are there.

Next up, try visiting your site's back-end with a different browser, ideally from a different computer. If it asks you for a username and password everything is working normally. What happens is that your original browser (the one you used to password protect the administrator) may have already cached the username and password. This is normal and all browsers do that. The idea is that they don't want you to have to type the same username and password every time you visit a page in the backend of your site.

If this still doesn't help, please ask your host if the support using .htaccess files. Not all hosts support that. If you are hosted on GoDaddy please note that you have to wait 10 to 30 minutes before any change in .htaccess files takes any effect. Moreover, GoDaddy being the crappiest of crappy hosts, doesn't allow using .htaccess in any directory except the site's root. If you are on GoDaddy my one and only advice is: change hosts, a.s.a.p.

Great! You can always clear Firefox' cache, quit it and restart it. When you try accessing your site again it will ask you for the username and password. I remember I had to do that a lot when I was developing and testing this feature :)
