Thank you for your quick response.
I've just replaced the lines with this code in class-aec-public.php
wp_register_style( 'jquery-ui-css', AEC_PLUGIN_URL.'public/css/jquery-ui_1.8.2.css' );
if( ! empty( $map_settings[ 'enabled' ] ) ) {wp_register_script( AEC_PLUGIN_SLUG.'-google-map', '//maps.googleapis.com/maps/api/js?v=3.exp'.$api_key );}
and in class-aec-admin.php
wp_enqueue_style( 'jquery-ui-css', AEC_PLUGIN_URL.'public/css/jquery-ui_1.8.2.css' );
if( ! empty( $map_settings[ 'enabled' ] ) ) {wp_enqueue_script( AEC_PLUGIN_SLUG.'-google-map', '
maps.googleapis.com/maps/api/js?v=3.exp'.$api_key );}
to fix the mixed content error and load the plugin locally from plugin folder to be independent from google servers. Second line will prevent Google Maps to load if Maps is deactivated in ACE settings.
For me this works great.
Is there an ETA or Roadmap for the next release?
Thank you.
