After installing quickstart package (Floox) I installed Acymailing pro and then was stuck, unable to logout of the site or login or do anything. This is the message I recieve: "Call to undefined function acymailing_getVar()"
After turning all Acy* unpublished via mysql I found out when the module "AcyMailing Module" is published, the error "Call to undefined function acymailing_getVar()" occurs.
Acyba indicates it could be a problem with your template overrides for AcyMailing.
Do you have a version of Floox that's compatible with AcyMailing Pro?
