After last Update error class.astinfo.php on line 221

Today i did the update as i do as usual. After updated i receive the message

Notice: Undefined index: lang in /var/www/html/admin/modules/dashboard/class.astinfo.php on line 221

Another strange symptom is that the right green bar (Web Server) become red. But the web server is working and if i reload the page the red becomes green for some time, after goes to red again. All other features seems to work without any problem.

The system Dashboard tool is 2.5.0.4

Any Idea?

thanks

Solved with new version 2.5.0.5

thanks
