Store Locator Plus® was recently updated to accommodate the latest Google Maps for JavaScript update which now requires a callback parameter. Third party hosted scripts such as the Google Maps for JavaScript library, a foundational component of Store Locator Plus®, can change how they operate at any time and without warning to the developers that employ these scripts. Thankfully the recent Google Maps change that makes a new callback parameter required only generates a warning. If this follows in the footsteps of prior Google Maps updates, it will one day suddenly be required and many sites that do not update the script deployment will fail.
For our clients using the WordPress plugins, this means you will need to update the Store Locator Plus® plugin before Google “flips the switch”. For our SaaS users, you do not have to do anything — we’ve already updated the library for you.
