It looks like the POST data is being lost when you submit it.

Check Manual:$wgServer and be sure you have the same server name you're attempting to use, so it doesn't try to redirect automatically between www. and non-www. hostnames.

The server access log might help diagnosing the problem, if you see that after the POST request there's a strange redirect.
