Please provide any additional information below.

selling works just fine, only buy is broken from what I can tell

I have exact same problem and do allso get those messages.

due to the fact that I posted this issue a week ago and haven't even seen so much as a "I'll look into it" response from either of the possible assignees, we have decided to remove this plugin.

I will leave the ticket up and perhaps the Author might be able to find the fix and notify the rest of you, but to me this plugin is dead and no longer has any use on my server.

I have recently taken the plugin over and will work on fixing the bugs

Hey, I'm not part of this project, but I fixed this problem for transitional use.
