I have the site as http://jr65.club and no www. what should I be looking for?

A problem has been detected with your web server that may cause your login to fail – if it does, click back and read the rest of this message. Some servers are poorly configured, and invisibly redirect traffic from one URL to another, and this invisible redirection results in lost submitted form data. Try changing your base URL in the config editor so that it contains www. then come back to this URL (make sure to refresh the page) and try again. There can be other causes, such as your server blocking web requests to itself. If problems persist, contact your webhost.

We'll clean up this error message for the next release to make it much clearer.

Thanks

So in RC3 (I think it was RC3, released about 5 hours after my last post here), we improved the error messaging a lot, and your site now shows this new messaging.

There were/are 3 distinct issues here…

1. The PHP curl extension was not installed. I've installed it for you.
2. PHP has this very weird bug regarding setting HTTP headers that was making the non-curl downloader fail for your server. I've never seen that one before. But installing curl removes this problem.
3. There seems to be some kind of queue or rate-limit on the server that still makes some of the HTTP calls to itself time out after 6 seconds. You can probably just ignore this problem. It's like 1 in 5 attempts. Composr doesn't need to download from itself except in a few special situations.
