Intellij Idea Code Completion not working

Question

I just started Intellij Idea ( version 13.1.4 )today and noticed code completion with ctrl + space doesnt work anymore. If i'm typing like a class the automatic popup still appears and i can autocomplete this way, but if i close the popup with esc i cannot open it with ctrl + space anymore.

My settings:

So Basic Completion is activated. I tryed:

• file-> invalid caches and restart

• power mode off and one

No difference. Any help appreciated cause it kinda makes me mad :)

I had this same problem. Ended up being caused by me not having a directory marked as Sources Root.

To fix: right click on your src directory > Mark Directory As > Sources Root.
