Omega theme file starts warning to be shown on front page [#2697599]

Hello,
I have just installed Omega for my drupal 8 installation.
But after installing Omega and setting it as default I've started getting error which I have no clue about.
Please help!

Warning: Invalid argument supplied for foreach() in omega_preprocess_page() (line 300 of themes\omega\omega\omega\omega.theme).
Notice: Undefined index: regions in omega_preprocess_page() (line 296 of C:\wamp\www\portal\themes\omega\omega\omega\omega.theme).

This is the first time I'm using this theme.... and am unable to see any headway in this.
Hoping for a speedy response.
Thanks,
Anisha

A little clarification here might help. The error on line 296 occurs first (duh!), and is causing the line 300 error.

And, in my case, it happens on every page, not just the front page (as the issue title says).

Ok, here's what I found. The function that gets the data that omega_process_page() uses is omega_return_layouts(). That function has this line...

  unset($layouts['_core']); // where did this come from??

And there is, in fact, a "_core" element in that array. However, "_core" also appears deeper into the array, for all the region groups ("all", "narrow", "normal", "wide"). Those "_core" elements don't have the "regions" index, thus causing the above errors.
