Because CouchDB is still alpha software we are still improving the core database format. Unfortunately, these changes are backwards-incompatible sometimes. If you stick to our official releases you can review our release notes, where we will always add warnings about breaking changes so that you can prepare your setup before doing an upgrade. However, there is hopefully a solution for your current situation. If possible, you need remove the current CouchDB installation (taking care to backup your CouchDB database files under `/var/lib/couchdb`) and fetch a copy of the original version you were using. The log files under `/var/log/couchdb` may be of help if you can't remember. If you really have no clue, you might have to each previous official release until you find one that works. Once you have installed an old version that works, and you can access your data again, you should download Christopher Lenz's CouchDB Python library from: http://code.google.com/p/couchdb-python/ It contains some export/import tools, seen here: http://code.google.com/p/couchdb-python/source/browse/#svn/trunk/couchdb/tools Use these tools to dump your CouchDB database to a separate file. Now, you can install the latest and greatest CouchDB version and use the same tools to re-import you data. Hope this helps, -- Noah Slater, http://tumbolia.org/nslater
