Thank you, I've downloaded the missing file and added the line: extension=php_sockets.dll to the php.ini
But I still get the erroe message. Since the path in the error message is C:\php5\php_sockets.dll I guess I need to change that to say C:\Program files\Vertrigo\php\php_sockets.dll. But where do I change it? I'm no programmer so this might be obvious to others
EDIT:
I copy/pasted the php.ini file from the wiki/installation and the problem changed. I now get this error:
Warning: dl(): Unable to load dynamic library 'phpext\php_mysql.dll'
But that file does exist, so why cant it be loaded?. Any ideas?
