wp_enqueue_script was called incorrectly

I don’t know how but now I am getting this error :

incorrectly. Scripts and styles should not be registered or enqueued
until the wp_enqueue_scripts, admin_enqueue_scripts, or
login_enqueue_scripts hooks. Please see Debugging in WordPress for

This is what I get when I try to log in… On other sites, I have only two first errors. I try to fix it but I can’t. Any suggestions?

Disable all plugins and switch to the default theme. It should be gone now.

Then enable each addon step by step, until the problem comes back. You know the source now, let’s say a plugin.

The plugin calls probably wp_enqueue_script too early. Find all occurrences of that function, then make sure they are bound to specific actions:

• wp_register_script() should be called for the action wp_loaded
• wp_enqueue_script on one of the actions
  • wp_enqueue_scripts,
  • admin_enqueue_scripts,
  • customize_controls_enqueue_scripts or
  • login_enqueue_scripts (see this thread for the latter).
