But this error is coming from the VM core! How could our template "work around" it?
You have to fix your error what ever that may be (I don't know what the error is)
I don't understand why you are asking here when this is a forum for supporting our templates and extensions - not Virtuemart?
There is a Virtuemart forum for that...
this error is saying you are trying to fire a vmcalculation plugin that doesn't exist any more
JPluginHelper::importPlugin('vmcalculation');
$dispatcher = JDispatcher::getInstance();
$calculated = $dispatcher->trigger('interpreteMathOp', array($this, $mathop, $value, $price, $currency,$this->_revert));
$calculated = $dispatcher->trigger('plgVmInterpreteMathOp', array($this, $rule, $price,$this->_revert));
//vmdebug('result of plgVmInterpreteMathOp',$calculated);
if($calculated){
foreach($calculated as $calc){
if($calc) return $calc;
}
} else {
VmWarn('Unrecognised mathop '.$mathop.' in calculation rule found, seems you created this rule with plugin not longer accesible (deactivated, uninstalled?)');
return $price;
}
}
the only vmcalculation plugin that I know of is the avalara one
