We are in the process of applying SP21 to our EP 7.0 SP16 landscape and have run into an issue with Visual Composer. When we run a VC app, we now receive the following popup:
*******************************************************************************
Communication Error
A communication error has occurred. Could not retrieve data.

Has anyone experienced this issue and if so what did you do to fix? Does anyone have any ideas as to what might be casuing this issue? Our VC apps worked just fine with SP16 before installing SP21
