Google does not openly advertise the fact that they have different location data for different users. However there is good anecdotal evidence an hearsay that Google Maps API returning inaccurate results may be by design.
The evidence is most prevalent in the geocoding of locations. The latitude and longitude Google assigns to different addresses is not “set in stone”. It is an interesting anomaly given the fact that places on earth should not move with regard to their latitude & longitude outside of plate tectonics.
The team at Store Locator Plus® has long held a theory that Google intentionally subverts accurate location data; quite likely to gain competitive advantage for their own products and services.
WordPress 4.9.9 as well as 5.0.1 and ALL the “security patch releases” back to 3.7 now have a new CSV file management bug. Any CSV file that is uploaded is rejected by WordPress due to a security violation.
The Quick Fix
Add this to your wp-config.php file:
Yes, this will effectively disable all those cool new “security features” in the latest release of WordPress but it also will get your CSV imports working again. Just remember to take this out when WordPress 4.9.10 (or 5.0.2) comes out — assuming they deem this new “security feature” a bug and patch it accordingly.
Recently updated to WordPress 4.9.9 or 5.0.1 and your CSV file imports for Store Locator Plus® stopped working? You can thank yet another “WordPress security feature” — also known as “backwards compatibility break”. This “update” came with absolutely no warning to plugin developers.
This does not affect our MySLP SaaS users thanks to our fully managed software stack, so they can rest easy and continue to import locations.
