Krita Fund website error when trying to change payment method

[Tyson Tan]

Hi guys,

My old credit card expired today, so I need to update my payment method 
on Krita Fund website. But when I clicked "Payment Method", the website 
returned an error:

Internal Server Error
There was an error handling your request. The error has been logged and 
we'll try and fix it as soon as possible.

If the error keeps occurring, please contact carl at carlschwan.eu.

Technical details
The exception was of type NoReverseMatch and said Reverse for 
'payment_method_replace' not found. 'payment_method_replace' is not a 
valid view function or pattern name.

Should someone be notified about this issue?

Best regards,
Tyson Tan
