Make sure the cache is turned on with minimum cache time of 60 seconds. Otherwise Twitter might ban you because of too many connections.

If it's on then it's probably your server that doesn't allow external connections in which case I can't do anything.

So it gets feeds from Twitter in RSS mode but not in XML mode?
Which version of Joomla is that?

OK, well then maybe it's a problem on connection between your server and Twitter. Try from some other server or localhost.

You said nothing about cache, I repeat: cache must be turned on and cache time minimum 60 seconds, otherwise Twitter will ban your server and maybe that's what happened.

Today I finally got a reply from twitter-support, but that was not really helpful - just a general template that my case either is a known issue or had been fixed, but no specific about my query

So, as the testing-period was over, I went ahead and registred the scroller (I need it anyway, also to display articles).

Could it be that perhaps the module requires any specifics from the PHP-installation which I may not have?

(In my last msg I mentioned trying from another J-install, I only got to do that today, but I now have the choice of a registered scroller-module (for another site) or an outdated test, so I'm afraid I couldn't do that)

Thanks Emir, I've emailed the details - pls.let me know if the email shouldn't arrive....

It's up to connection between your server and Twitter. Can't do anything about it.

Because it looks like those are on different servers and services, Twitter is huge. I tested it with previous customer and that's the only conclusion I came up with. On my server everything works great.
