Not sure if it is actually this module that is causing the error but this is how it happened:
I installed my website on a server and then moved to another server.
After copying over both the database and root folder, I started getting this error.
BTW, I thought of trying to upgrade to the latest dev version 7.x-1.x-dev but it didn't help.
You can see the error on my website: http://www.2bwebsite.co.il/en
