Hi, after a successful upgrade from 2.4.6 to 2.5.1 almost everything works, apart from the search function in the web frontend. In production.log there is the following error message: ==== [c82cffa0-322f-4d8a-b6e3-a2b520284c29] [24886:84443.08] ThinkingSphinx::ConnectionError (Can't connect to MySQL server on '127.0.0.1' (111)): mysql2 (0.3.14) lib/mysql2/client.rb:67:in `connect' mysql2 (0.3.14) lib/mysql2/client.rb:67:in `initialize' thinking-sphinx (3.0.6) lib/thinking_sphinx/connection.rb:60:in `new' thinking-sphinx (3.0.6) lib/thinking_sphinx/connection.rb:60:in `initialize' thinking-sphinx (3.0.6) lib/thinking_sphinx/connection.rb:15:in `new' thinking-sphinx (3.0.6) lib/thinking_sphinx/connection.rb:15:in `new' thinking-sphinx (3.0.6) lib/thinking_sphinx/connection.rb:27:in `block in pool' ==== How do I get by this?
