Could not create instance of type: Sitecore.Data.Database error while Installing a Sitecore module on CD server

Question

I imagined this would be fairly simple given the lack in posts about it (anywhere really) but we're hitting a bit of a problem with this one.

The module in question is URL Rewrite. It's installed fine on the CM server and it all works there. Getting it onto the CD server on the other hand is proving difficult. I've published the content to the web-live database.

I've manually copied all the files from the install package into the appropriate places on the CD server but it brings the entire site down giving the error:

Could not create instance of type: Sitecore.Data.Database. No matching constructor was found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Were running on Sitecore 8.0

Thanks in advance

Answer 1

After going through all the files in the package and checking the content of them I found the culprit. There was a file (Hi.UrlRewrite.Prefetch.Master.config) which references the master database which obviously doesn't exist on the CD server. Removing this file stopped the site dying and the redirects now work.
