PHP Warning: array_key_exists() expects parameter 2 to be array

Hello Eder,

Based on what you described, I suspect there may have been an issue during the migration.

It looks like the code it is trying to retrieve an option from the wp_options table, but it’s being passed as a boolean instead of an array.

Firstly, try temporarily switching to another theme, like default themes like – Twenty-Twenty or Twenty-Nineteen, and check if the error or issue persists.

Next, you can deactivate all the plugins temporarily and see if that solves the error. If it does, activate plugins one by one to see which plugin is causing the problem.

Hello @paulam11

I had already done all these tests but the error persisted.

So that I could solve it, it was necessary to edit lines 184/185 to confirm that it is an array:

if (is_array($saved)) {
    $key = array_key_exists('sfwd-lessons_lesson_video_url', $saved) ? 'sfwd-lessons_lesson_video_url' : '';
    $key = array_key_exists('sfwd-topic_lesson_video_url', $saved) ? 'sfwd-topic_lesson_video_url' : $key;
}

Could you pass on to the team responsible for programming? This check does not modify the function, it just guarantees to pass a valid array before array_key_exists.

thanks.

Thanks! We’ll get this fixed.
