Hi there,
Ah, looks like the Azrul System Mambot is not properly installed or you are accessing your site incorrectly.
Here is what you can try, try accessing your site with the mosConfig_live_site value that you have set in your configuration.php file.
Secondly, ensure that the file exists when accessing
http://yoursite.com/mambots/system/pc_includes/ajax_1.2.js . If the file does not exists, uninstal "Azrul System Mambot" from your mambots manager. Then ensure that the directories below are properly removed,
JOOMLA/mambots/system/pc_includes/
JOOMLA/mambots/system/azrul.system.php
JOOMLA/mambots/system/azrul.system.xml
Then install the attached installer. After installing the mambot, proceed to the Mambots manager and publish the "Azrul System Mambot".
