Have someone configured centova 3 in whmcs for automatization?
I still have errors and the support does not help me.

Its the weekend, probably won't get to much help from official CC support.

What errors are you getting?

"Order Accept Encountered Problems

Socket error accessing http://s3.webradio-hosting.com:2199/api.php: fopen(http://s3.webradio-hosting.com:2199/api.php) [function.fopen]: failed to open stream: no suitable wrapper could be found"

The strange thing is that fopen() is enabled.

I really don't know how to solve this.

So nobody use whcms and centova 3 configured for automatic setup?

Socket error accessing http://s3.webradio-hosting.com:2199/api.php: fopen(http://s3.webradio-hosting.com:2199/api.php) [function.fopen]: failed to open stream: no suitable wrapper could be found"

This error is coming straight from PHP on the WHMCS server and doesn't have much to do with us.

We've had an anecdotal (unconfirmed) report, though, that the 'Secure' checkbox (after clicking Servers and then clicking on your Centova Cast server in WHMCS) might have something to do with this.  Try un-checking it if it's checked.

The strange thing is that fopen() is enabled.

Not strange at all -- it's not saying fopen() is disabled.  It's saying there is no suitable wrapper for the URL scheme used to access Centova Cast -- specifically, "http".  That would normally indicate that either URL fopen wrappers have been disabled in php.ini (nb: that's very different from disabling fopen itself) or that PHP itself was built without HTTP client support.

Also, wrong forum.  Moved.
