I have just installed OT Countdown plugin. I have Joomla! 3.3.6 Stable [ Ember ] 01-October-2014 02:00 GMT and VirtueMart 3.0.12.
I go to the Extension>Extension manager and install plugin.
Next, I go to Extension>Plugin manager and click "OT CountDown Discount for Virtuemart" on the list. In the settings I change status to "Enabled" and save.
I follow 2 steps from "Plugin" tab: make a promotion and assgin it to products.
Final effect: in shop there is promotion but no clock. Could You help me? What I have to do more to see clock?
