I copied an instance of WP from one domain to another. Copied the files, backed up and restored the database, edited the MYSQL db to update to using the new domain, etc.
The only thing that I can't get working is WP Super Cache.
It's telling me wp-cron.php is not found. It is clearly there, and scheduling posts. But super cache isn't seeing it.
I checked my DNS files and they all have localhost pointing to 127.0.0.1 or whatever they're supposed to be, and that's the only a record for that IP.
