But as I am not a Joomla/CB/FB expert, got lost in that thread
I tried to install uddeIM 1.4 (com_uddeim14.zip) through the extension installer in Joomla but got the following message:
uddeIM Instant Messages for Mambo/Joomla Critical Error: Failed to write to configuration file: /home/yasiyoru/public_html/administrator/components/com_uddeim/config.class.php
uddeIM installation complete.
Please continue to the administration backend and review the settings.
* If you are running the CMS in a character set other than ISO 8859-1 make sure to adjust the settings accordingly.
* After installation, all uddeIM e-mail traffic (e-mail notifications, fotgetmenot e-mails) is disabled so that no e-mails are sent as long as you are testing. Do not forget to disable "stop e-mail" in the backend when you are finished.
* Important: When you have upgraded uddeIM from an earlier version please check the README. Sometimes you have to add or change database tables or fields!
