Fatal error mysqli_sql_exception in wp-maintenance-mode

Hi @artiomrudenco,

Thank you for using our plugin, it looks like this is a duplicate of an issue here – https://www.ads-software.com/support/topic/fatal-uncaught-mysqli_sql_exception/#post-16451626

Can you try to re-install the plugin if your WordPress is up-to-date? Thanks!

Hi @bvytis ,

I got same problem on other APP.
Could you check it please?

@bvytis
I don’t think is related, but trying to catch error (found reason) I got another error on localmachine (query monitor):
Warning Undefined array key “social_instagram”
According to Modules menu -> It is not mandatory.

1. wp-content/plugins/wp-maintenance-mode/views/settings.php:734
2. WP_Maintenance_Mode_Admin->display_plugin_settings()
