Content Analysis gets stuck at loading. All suggestions welcome!

Hello,
I recently installed this module on a client's site, and apparently everything works great except for the content analysis feature. As soon as I click "Analyze content" in Content Analysis tab, and window pops up trying to load the results but it won't go pass the loading animation. It was working fine before I had the readability module and alchemy sdk setup, but I doubt if those are the reason for conflict and that it's some sort of javascript issue. Any kind of help or suggestion is welcome...
