Phenomenon:

When accessing to the AEM you get the following error message.

 

 

Cause Analysis:

This issue is relating to the IIS configuration.

Solution:

 1. Back up the file applicationHost.config under the directory C:\Windows\System32\inetsrv\config.

2. And then copy the file applicationHost.config to the other directory to do modifications because Windows doesn’t allow you to modify this file under the directory C:\Windows\System32\inetsrv\config.

3. Supposed that your Appeon server is installed on the Default Web Site, then please find the following line in the applicationHost.config file.

<location path="Default Web Site">

<mimeMap fileExtension=".css" mimeType="text/css" />

4. Please modify the line above into the following and save the changes.

<!-- mimeMap fileExtension=".css" mimeType="text/css" /-->

5. Use the modified file applicationHost.config to replace the one under the directory C:\Windows\System32\inetsrv\config.

6. Restart the IIS.
