This report does not impact users of the My Store Locator Plus managed locator service.
The WP Store Locator Plus version release 4.9.15 update will throw fatal errors with third party add-ons if you are using DeBaat User Managed locations (UML) or DeBaat Social Media Extender (SME). We are working on the Store Locator Plus 4.9.16 release to prevent the “white screen” and auto-deactivate the outdated add-ons.
Resolving SLP 4.9.15 White Screen
This issue only seems to impact third-party add ons including Social Media Extender and User Managed Locations. It MAY impact Gravity Forms add ons as well.
To resolve this issue you need to determine how important those add-ons are to you.
