The reason I have found this error is because the module won't let me submit a comment-- the buttons are greyed out and unresponsive.
Looking into it, upon init of the module on my K2 integration, my console is throwing this error:
Uncaught TypeError: Cannot read property 'commentlist' of undefined in komento.commenttools.js:1
It's a minified js file, with obfuscated object names, so I'm having a hard time debugging it. I currently don't have any SEF or mod_rewrite enabled, and it appears all the included scripts are being loaded.
