Hi everyone,
I've found today editing any page triggers this fatal error:
Fatal error: Uncaught Error: in_array(): Argument #2 ($haystack) must be of type array, null given
in /wp-content/plugins/oxygen/component-framework/includes/conditions.php on line 743

We are running oxygen 4.4, I've upgraded to 4.5 and downgraded to 4.3 with no difference, I've tried a few more things (uninstalling plugins etc) but nothing works. It seems yesterday's backup of the website hasn't got this issue.
I was wondering if anyone has seen this issue before? I'd like to make sure we don't end up in this scenario again.

Thanks for any help
Olga
