Hi Brad, after many days of headache and losing the contents of my site, I got so frustrated and decided to rebuild 2 sites with WP. Yes, I used openhost, and yes I also believe they have changed something for v2.3.3 to stop working. I think there is nothing wrong with my code, as I have been quite careful. When I tried to do a clean install of v2.3.3 it just wouldn't even let me, are you experiencing the same prob?
I think it will be best if you contact openhost, and ask to see if they have changed anything, if you still want to stick with SS for your site.
I have a SS site that is using v2.3.2, and still running under the openhost server. All the best of luck, and I hope openhost will help you resolve your install! Please let me know how you get on.
Cheers!
