Thanks for that. The customer/order export issue ended up being an issue on SkyVerge’s end with their Legacy CSV Format option for exports. They made a note of it to the developers, but I just switched to a different format and exports worked normally after that. Since the error was referencing a call to undefined function in woopress core I thought the issue might be there, but nope. Thanks so much for all your help. I think everything is resolved at this point!
