Undefined index warning post-activation
-
After activation, anywhere that this plugin’s code gets called (Customizer > Widgets, or Widget Options), the following warning will appear if WP_DEBUG is enabled:
Notice: Undefined index: q2w3_fixed_widget in /[domain server path]/html/wp-content/plugins/q2w3-fixed-widget/q2w3-fixed-widget.php on line 175
I’ve seen this in a few other plugins too. Once you save options and refresh the page, the warning goes away.
