Hello,
I just set up your plugin on my site and it has totally taken my site down - here is the URL: http://www.strategycms.com.
My site is hosted on Rackspace Cloud Sites and that may be part of the problem (they say that they are not set up to deal with a plugin of this sort - that their load servers don't know what to do with the information, I don't know exactly what that means, and that there is nothing that they can do).
Either way, what happened was I put the two files in the appropriate folders, uncommented the sunrise line in wp-config and then tried to go to Site Admin in the backend, but I couldn't. All I get is a blank screen (on another computer I got a 500 Error).
I deleted the files from the backend and recommented the line in wp-config, but that didn't help.
My error logs show the following message:
[04-May-2010 14:14:01] PHP Parse error: syntax error, unexpected ')' in [NOT SHOWN FOR SECURITY REASONS]/wp-config.php on line 120
This is the line in question (the last line of wp-config):
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
ABSPATH . 'wp-settings.php');
What can I do to get my site back? Please let me know and please put in a warning on your front page in large letters that your plugin is not compatible with Rackspace Cloudsites (and perhaps other cloud servers).
Thanks and be well,
Moshe
