I've been having little glitches here and there and the latest one relates to authorize.net not working and orders getting lost.

The miva experts on the miva forum have told me that the miva engine West Host uses is buggy and slow and they should be updating to the most recent one, which is 4.10.

SO....Does West Host have v4.10 ? How do I go about upgrading?

THANKS,
Dottie
