Calendar.Setup error in Jomsocial

Calendar.Setup error in Jomsocial when JFBConnect is installed. This also affects all editor plugins.
We went through disabling each plug-in and found that JFBC is the cause of the calendar.setup pop-up error as seen below.
This is quite serious and is halts the use of the site until the user acknowledges the error twice and also it does not allow the front-end article editor to load correctly.

I discovered there was a secondary plug-in causing a conflict with both JFBC and joomla. This plugin has been remove and all is fine.

Hi,

I am experiencing the same problem. (Calendar.setup: nothing to setup (no fields found): check your code.' ) Which plugin did you disable to resolve the problem?
