Hi, I have developed a site that has a couple of site collections below the root. I have deployed this site into a staging environment and everything worked fine, but as soon as the site went into a production environment I got the Invalid List Template error when trying to access certain sharepoint pages like the Manage Content and Structure or the View Reports. I used the same site collection template that was used to create those to create a new one and it worked fine. It just seems to be all the site collections below the root that were created before deploying. I have tried restoring the content db from the staging environment to the production environment but that didn't fix anything. Does anyone know why this could be happening? Any help would be appreciated! Thanks! UPDATE: All of the sub sites in the site collections were also broken and when I checked I saw that the references to masterpages have changed back to the default.aspx. Once we updated the masterpages to point to our custom masterpage the subsites started working again. We still have the problem with the Manage Content and Structure and View Reports pages.

can you check if any features is not enabled on all of those subsites. may be enterprise feature or some other feature.Aniket

It seems that the list templates that were being copied over to the production environment were corrupt. We got the original source files and copied them straight to production and this fixed the issues.
