This common error has puzzled many website developers, leaving them scratching their heads for a solution. But fear not, we're here to help you unravel this conundrum and get your page loading smoothly once again. In this article, we will explore the main causes of the error and provide easy-to-follow solutions to help you move past this roadblock. So let's dive in!

Understanding the Error:

The error message you encountered - "Error to use a section registered as allowDefinition='MachineToApplication' beyond application level" - might sound intimidating. However, it essentially means that there is a conflict with the configuration files (web.config) in your website's directory structure.

Common Causes:

1. Missing Application Configuration: Many times, this error occurs when the /portal/ directory is not properly configured as an application in IIS (Internet Information Services), even though you have followed the instructions.

2. Nested web.config Files: Another common cause is having multiple web.config files in your directory structure, particularly if there is one in both the root directory and the /portal/ directory.

Solutions:

Now that we know the common causes, let's explore some simple and effective solutions to overcome this error and ensure smooth page loading.

1. Solution 1: Configure /portal/ as an Application in IIS:

   • Open IIS Manager.

   • Right-click on the /portal/ directory and select "Convert to Application".

   • Follow the prompts and ensure that you have chosen the correct application pool for your website.

   • Save the changes and restart IIS.

   📝 Pro Tip: Double-check the configuration to ensure that the /portal/ directory is configured correctly as an application. Sometimes, the error can be due to a minor oversight.

2. Solution 2: Merge web.config Files:

   If you have a valid reason for having a separate web.config file in the /portal/ directory, you can try merging the configurations from both web.config files. Remember, merging web.config files needs careful consideration and could potentially introduce unforeseen complications. It is advisable to have a backup of your original web.config files before proceeding.

   • Open the web.config file in the /portal/ directory.

   • Identify and remove any sections that are already defined in the root web.config (e.g., <customErrors>, <anonymousIdentification>, <authentication>, or <membership>).

   • Merge the remaining sections from the /portal/ web.config file with the root web.config file.

   • Save the changes and restart IIS.

   📝 Pro Tip: Before merging the configuration sections, double-check that there isn't duplication or conflicting settings, which could cause further errors.

Conclusion:

By following the solutions outlined above, you should be able to overcome the frustrating "Error to use a section registered as allowDefinition='MachineToApplication' beyond application level". Ensure that the /portal/ directory is configured correctly as an application in IIS, or consider merging the configurations from both web.config files. Remember to be cautious while implementing any changes and make backups to avoid any potential mishaps.
