well, sh*t happens: Yesterday I accidently rsynced the current 2.1-trunk with my Live-Site and run the upgrade-script, though I wanted just update form 2.0.4 to 2.0.5. Now all my ?page_id-Links don't work anymore. And managing pages isn't possible, there are no existing pages shown to manage. Though I still can access the pages with ?p=SOMEID.
Is it safe to just copy over the 2.0.5 release? Any recommend desaster recovery strategies?
