Hi,
After switching a php app from php7.3 to php7.4 on Azure App Service I get the following error message:
HTTP Error 500.0 - Internal Server Error
D:\Program Files (x86)\PHP\v7.4\php-cgi.exe - The FastCGI process exited unexpectedly
Most likely causes:
- IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
- IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
- IIS was not able to process configuration for the Web site or application.
- The authenticated user does not have permission to use this DLL.
- The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.
Detailed Error Information:
