Our CC processing is working fine for all other customers but we have some with a different account class when I try and run their cards I get. [Plugin Warning] Unknown Internal Error; WARNING: transaction may have completed!! Please check your Transaction batch. Any ideas? Thanks
I have two in add/remove, 1.2.2 and 1.4.2_05, but just an fyi this is happening on multiple workstations. And CC processing works fine for anybody without the different account class
DONE, but now I get. The merchant login ID or password is invalid or the account is inactive. I did try an account without the different account class and it went through fine.
Sounds like you have different merchant settings for the different account class. I would double check it under Maintenance & Preferences -> General Preferences -> More -> Merchant
