Is there something that changed that would remove the database debugging/icon from the web toolbar? I have a number of legacy sites that no longer have the database icon on the toolbar after updating to 1.5.15. I have 1 propel site that does have it still but I can't see anything different in the configuration files, nothing else changed on these sites. web_debug is set to true in settings.yml, DebugPDO is used in databases.yml, and the controller is set to load the debugging environment. Sites running doctrine are unaffected.
