WP Wall error

Hello. I’m trying to get the WP Wall to working on my site. As soon you try to comment you get the error “An error occurred, please notify the administrator” This is both as member and guest. The official fix for the plugin is to chmod 755 on all files that are in WP Wall folder. Have already tried that on all files in /oblivion/chat were I can see the WP Wall plugin is located that are included with the theme. But still getting same error code.

Is their something I’m missing with setting the plugin up?
