Hi,
First thread is talking about a fatal error.
Do you have a fatal error ?
Second thread did not provide any error or details which helped us to understand the real issue.
That second thread is also very old compared to lot of threads talking about upload issues.
Because you do not have the same errors that the other threads ; and because you already read these threads means that you already know that we need details about the PHP fatal errors (it was the first questions we asked).
So please ; explain your issue with details and provide us information about the PHP error log.
