These are some pretty convoluted installation instructions.

I found a couple of bugs when trying to use this under 1.5.0. In index.php under the admin/plugins/chatterblock directory.

The symptom was that whenever you tried to save any config changed, you ended up with a blank page (because of an error in the cb_config.php file in the chatterblock cache). This error was due to what looks like a cut and paste error in the code in index.php. The value of the userprefs access was not being stored correctly. Also, there was no provision to store the value for the name displayed when anonymous posts are added.

Here is my patch:

I just encountered the same issue. So it seems this bug hasn't been fixed in the released code in all this time (you posted about this back on August 21 2008, and it's January 18 2009)! : (

Thank you for posting the fix - *much* appreciated!
