We are trying to transfer an Umbraco 4 website to new hosting. We've moved all the files and the MS SQL database successfully but there seem to be problems with the [url removed, login to view] file. We are just getting an error. I have little to no experience with Umbraco and Windows Server. The site was working perfectly on the old hosting and the [url removed, login to view] has not been changed, but something isn't happy. I'm sure this will be pretty simple for someone with any experience to fix. The budget is flexible if there are further problems discovered.
