I have got a bit further now that when I try to connect to providence I get the CA logo in the top left corner of my browser with a text entry box underneath it but this is where the system hangs. I f I look in the apache2 error log I see this - PHP Parse error: syntax error, unexpected '.', expecting ',' or ';' in /var/www/html/providence-develop/app/lib/core/Media/MediaViewerManager.php on line 49 .And this is a copy of that line 49 static $smediaviewerplugindir = __CA_LIB_DIR.'/core/Media/MediaViewers'; - I see that __CA_LIB_DIR is required once in the AuthController.php . Is it possible that this error is related.
