OK, so I've just done a 1.8 to 1.9 upgrade.
All is well but my custom payment provider 'Configuration' panel won't show (i.e. ConfigurePaymentMethod.ascx)
Any ideas why this maybe ?
I've checked the location of the module in the 'ConfigurationTemplatePath' field and that is just fine.
Nothing showing in error log and the payment method itself works just fine.
Any ideas ? thx
