Redmine

Team,

I have tried installing backlogs plugins which made me to travel some worst path and finally installed the required
plugins like nokogiri, xapian-full....etc but after upgrading most of the components am getting an error on browser like this

Error message:
undefined method `alias_method_chain' for CGI:Class

Exception class: NoMethodError

Application root: /usr/share/redmine
