AJAX Recommend: Request failed

Joomla 1.5.23, latest PHP, my admin emails work, and whether I set "From" to admin or user, I get "request failed".

I'm using jQuery and Mootools from Google (latest) via JB Library.

Any suggestions?

Here is the site, but I had to turn the AJAX module off because it is live.

I can add the module to an "unpublished" menu page if you need to see the problem.

Thanks!

Please do and send me the direct URL.

Thanks, Saka.

I sent you an email.

The "modules/mod_ajaxrecommend/mod_ajaxrecommend.php" was set to 644 instead of 755. And I had a custom htaccess file that was excluding direct access to that file. After adjusting these, everything works.

Thanks, Saka. ;D
