What do you mean?
Fiexed. Try the version 1.04.
Download the new release and upload it. You needn't uninstall and install the plugin.
Check if the theme uses this widgetzone
PublicWidgetZones.BodyEndHtmlTagBefore
Maybe you removed it.
You should open the file Checkout/Completed.cshtml.
This file has a model OrderModel.
Use this file.
Please upgrade the plugin and try it. Write to me about the result.
