I have a php application which I have been hosting on IIS that has suddenly stopped working and returns a server 500 error. In an attempt to troubleshoot it I have added a Failed Request Tracing Rule with a scoop on 500 errors and this was the results.
109. view trace Warning -MODULE_SET_RESPONSE_ERROR_STATUS ModuleName FastCgiModule Notification 128 HttpStatus 500 HttpReason Internal Server Error HttpSubStatus 0 ErrorCode 0 ConfigExceptionInfo Notification EXECUTE_REQUEST_HANDLER ErrorCode The operation completed successfully.(0x0) FastCgiModule
Although the error is not crystal clear, I have read that in FastCGI I can change Standard Error Mode from "Return Error in 500 to "Ignore and Return 200" but that doesnt seem to work.
I have seen it suggested that the application pool be changed to local system and I have also set php version in php manager but nothing is solving the issue.
Grateful if anyone could assist a setting that would allow me to see exactly what's causing that error..
