For the login connection error, please try connecting to ExtremeCoderz.com. If you aren't able to connect I'm guessing your IP is banned from the server and this is why you can't login.

As for the post crash, please check your templates. Sometimes this happens from bugged templates that have some HTML encoding inside them. For example: #374. If your templates look weird, remove them.

It sometimes crashes on me too while posting even though my templates are good. But I'm patiently awaiting the new version.
