VirtueMart version 3.0.2 running on Joomla 3.3.6.
Error message shows as:
vmError: Unrecognised mathop in calculation rule found, seems you created this rule with plugin not longer accesible (deactivated, uninstalled?)
It is being caused by the tax calculation rule. I have setup rules exactly the same on many different websites - first time I am having a problem with this.
Settings for the tax calculation rule have been set as follows:
Calculation Rule Name = IN Sales Tax
Description = Indiana Sales Tax
Type of Arithmetic Operation = Tax Per Bill
Math Operation = +%
Value = 7.0000
Currency = United States Dollar
Product Category = Available for all
Shopper Groups = Available for all
Country = United States
States = Indiana
Manufacturer = Available for all
Start Date = 01/28/15
End Date = Never
I've re-saved, deleted, re-created, still has the problem.
I also tried to set "Type of Arithmetic Operation" to "Tax per Product" and it never shows up in the cart.
Just updated to VirtueMart 3.0.4 and it seems this problem has been fixed.
