Has anyone come across the following error when deploying the Esri Maps for SharePoint 3.0.1 solution to SharePoint:

***** SOLUTION DEPLOYMENT *****

Any ideas? All pre-requisites have been met and checked.

Hello Andy,

The errors you are providing above seem to be indicating a possible issue with the SharePoint site itself more than with our Plugin. Please refer to the following Microsoft Document:

Deployment error "The web.config is invalid on this IIS Web Site"

I believe working with your SharePoint Admin on this issue might be more beneficial. Please let us know if there is anything more we can help with. Thanks-

Justin
