Http Error 500.19 - Internal Server Error

Error Code 0x8007000d

Config Source -1: 0:

This error can occur when the web.config file contains invalid xml. It can also occur when the file contains xml related to some module that is not installed, typically the UrlRewrite module. Try commenting out the rewrite element in the web.config file. If that resolves the error, install the UrlRewrite module by doing a web search for install UrlRewrite module and following instruction. After installation, the rewrite element can be restored.
