Hi,
Not sure if this has been reported yet (looked but didnt see). All I did was as follows:
o downloaded and extracted nopCommerce2.40 onto a new folder
o copied Settings.txt file from nopCommerce2.30 App_Data folder onto nopCommerce2.40 corresponding folder
o created backup of nopCommerce23 database
o restored backup of nopCommerce23 database onto nopCommerce24
o ran the upgrade.sql script
o started VS and ran it
o The default store is displayed without issues
o Click on New Products and get the following:
Object reference not set to an instance of an object.
on line 239 of the TaxService.cs file
//get tax rate
239 var calculateTaxResult = activeTaxProvider.GetTaxRate(calculateTaxRequest);
if (calculateTaxResult.Success)
{
//ensure that tax is equal or greater than zero
if (calculateTaxResult.TaxRate < decimal.Zero)
calculateTaxResult.TaxRate = decimal.Zero;
return calculateTaxResult.TaxRate;
}
