XML-RPC Error (28194976) Please help

Hi

I am using hikashop shopping cart.
If a user pays by eft and I need to manually change the status to "Confirmed" I get the following Error message
"XML-RPC Error (28194976): Calling parameters do not match signature | ERRORCODE: "

If I refresh the system shows status as "Confirmed" but the user is not enrolled into the course

What must I do!!

I have added the additional functions in Moodle but it has not helped

What's the SKU of the item? If the SKU is fine (course ID in Moodle, as set by Joomdle) that error should not appear.
Maybe you changed sku manually?

None of my moodle courses had iDs, I have now added the same ID that joomdle shows for a product the that product in moodle.

On Joomla in Hikashop I am using options so 1 Joomdle product has options such as "Online" or "Facilitated class" as a result even though the produck ID is 66 the final code is 66_2_1 for example.

Does this mean I need to split all the products up? This never used to be a problem could it be1.0.6 that is causing this

> None of my moodle courses had iDs, I have now added the same ID that joomdle shows for a product the that product in moodle.

The ID I refer to is the database ID, nor the ID you can set in course set up.
These ids are just integers: 2,3,4...

If code of the product is 66_2_1 instead of 66, it won't work. There is no changes on this in 1.0.6, so I think this should fail the same on previous versions.
