issue with plugin to make a child-theme

Hi guys,

Today I’ve bought the Opstore-Pro templates.
The demo is loaded, plugin installed and activated.
Time to make a child-theme all works perfectly till I’m hitting an error:

Notice: Trying to access array offset on value of type bool in /var/www/vhosts/##domain-excample.com##/httpdocs/wp-content/plugins/sale-alert/sale-alert.php on line 98

function show_sale_alert(){
global $post;
$sale_alert_settings = get_option(‘sale_alert_save_settings’);
$enable_popup = isset($sale_alert_settings[‘popup-enable’]) ? $sale_alert_settings[‘popup-enable’] : 0;
>>>>> $pages = $sale_alert_settings[‘checkfield’];

I’m pretty good reading code but this no idea where to look with this error. For now, I’m trying to work around it so I can work on the layout of the template.

(plus another little typo error but that’s fixed and send an email about this.)

Best Regards,
