This may not be a new issue but may be related to the cu_away_new.sql comments.
I installed correctly, putting the extension folder in with the extensions and added the following to my LocalSettings.php:
$wgChatKicks = true;
$wgChatSocialAvatars = true;
$wgChatRichMessages = true;
$wgChatUseStyleAttribute = true;
$wgChatSidebarPortlet = true;
$wgChatLinkUsernames = false;
$wgChatMeCommand = false;
$wgChatMaxMessageLength = 1000;
When you visit Special:chat you will see that it does not show any users or my text.
In Chrome, in the console I see this:
Uncaught TypeError: Cannot read property 'users' of undefined.
My cu_away_new.sql file reads:
ALTER TABLE /*_*/chat_users MODIFY cu_away binary(12)
Are there any extensions I should have that are needed for this to work or is there a way to start over and install it correctly? I started off with the update.php but there was an error associated with the cu_away_new.sql. I changed this file to incorporate the new text and then ran it again and the error during update.php did not occur this time but the results were the same.
