Suggestion not showing up automatically

Hello,

As the title suggests, since this morning the suggestions popup stopped showing up automatically when I type.

But it shows up just fine when I press Control+Space...

These are my settings :

I tried:

• disabling all my settings
• disabling then enabling suggestions

I'm using Archlinux and the latest version of PhpStorm.

Thank you in advance for your help.

EDIT: I only have this problem in my .php files, .css files are working normally ??
