Do you have any caching on this site?
No, I had disabled the caching plugin (w3 total cache) previously. This occurred since that.
Did you also delete the cached files. Sometimes the cached files (if its there) will continue to show cached page even if the plugin is deactivated.
Try emptying the cache and do a new test transaction. Let me know how it goes after that.
