Earlier this year I had the pleasure of handling the following error:
HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.
Config Source: <staticContent> <mimeMap fileExtension=".woff2" mimeType="application/font-woff2" /> </staticContent
I removed the above
mineMap from my
web.config file and this solved the problem. The problem was that the hosting company I used had updated the configuration of their IIS. Adding this mime type to the general configuration. By removing this line everything worked as intended. An alternative fix would be to adjust this in the IIS.
