faced a issue while creating a site from a site template. Below is a screen shot of the error.
This error pops up if the site has been restored from a installation where Reporting Services has been installed on Integrated Mode and then restoring the site to a installation where there is no reporting services installed. The content types do not match and hence the error.
Solution:
Install Reporting services in Integrated Mode on the new server and then uninstall the Reporting services feature. This will delete the content types. The re-create the site template and create sites using the template.
