I've tried different approaches to get solr to work, in particular, these rake sunspot:reindex rake aborted! RSolr::Error::Http - 404 Not Found, but I've ended up with this yet:
$ bundle exec rake sunspot:reindex
=> Solr server started
rake aborted!
RSolr::Error::Http: RSolr::Error::Http - 404 Not Found
Error: Not Found
URI: http://127.0.0.1:8983/solr/default/update?wt=ruby
Request Headers: {"Content-Type"=>"text/xml"}
Request Data: "<?xml version=\"1.0\" encoding=\"UTF-8\"?><delete><query>type:ActsAsTaggableOn\\:\\:Tag</query></delete>"
How to fix it?
