It's simple. Rename plugins/system/admintools/main.php to main.bak.php. This will disable the Admin Tools plugin which is responsible for effecting the security measures on your site. After you fix the problem, remember to rename the file back to main.php ;)

That function works on all sites, including the Joomla! Magzine site right now :) Kareebu secure is a fork of jSecure which runs pretty much the same PHP code as the Admin Tools feature (really, there is only one way to do it).

The reasons I can think that this didn't work:
1. You used non-ASCII characters in your secret word. If you do that, you have to URL-encode them when using the secret word on your site. For example, if your secret word is "this&that" you have to access your site's administrator as http://www.example.com/administrator?this%26that

2. You used one of the characters Joomla! or your web server will automatically strip out, such as , &, ?

3. You are using some other feature which blocks out access to your administrator area, also handled by the same plugin, such as the Administrator IP Filter. In this case I strongly suggest disabling those features and try to implement one security feature at a time.

FYI, it is impossible that the secret word feature is not supported by any host out there. The secret word matching takes place during the administrator page initialization phase, before you login, checking what you have entered in the URL to access your site's back-end. Except for the three aforementioned reasons there is no other way this feature won't work.

The password is good. However, the IPwhitelisting might be a very bad idea unless you have a static IP. This usually is an extra feature you have to specifically ask your ISP for and is charged extra. Do note that "ISP" refers to the company managing connection from your PC to the Internet and has nothing to do with your site's hosting provider. I think that by simply removing your IP from the whitelist and turning off that feature will be adequate to get Admin Tools to work as you expect it :)

No problem! We are here to help. I'm glad we got that working on your site :)
