Same problems with dashboard unresponsiveness since last upgrade. Running WordPress 4.4.2 and All-in-One Event Calendar 2.3.8. Disabling the plugin returns dashboard to normal responsiveness. I am unable to edit event details in any event and can not access Advanced menu. Clicking on event detail sections or Advanced settings menu does nothing.
My developer fixed the problem. He added CSS code to override the info window’s text directly, applying the styles to the theme’s stylesheet.
Thanks, but option 1 changes the entire map to black so you no longer see the map. Is there code to change only the info window?
