been having this issue for a few days now and i don't know if anybody else has experienced it. By default the only payment method that is activated in my store is the one linked to my payment processor. Lately i found out that it would be turned off while the saved cc option would be on, all this without me doing anything. I have tried to fix the issue by turning off the saved cc option and restoring the other one. To my surprise the same thing will happen hours later or the following day.
Does anyone have any insight into this issue. I recently started having this issue and I am not sure if this is a hacker turning this on or some other issue.
