Maps Marker Pro v4.20 with CSV rewrite and lots of improvements & fixes is available

Maps Marker Pro v4.20 has just been released – later than announced, as good things need time :-). This release includes lots of  with a several new features, library updates, optimizations, performance improvements and bug fixes – in some cases based on your feedback, thanks a lot!

For details and other highlights about this release please see below. An updated to the latest version is – as always – highly recommended. If you access to updates and support has expired, please click here for more information on how to optionally renew your access.


rewrite CSV import

Maps Marker Pro allows you to easily perform bulk updates on markers by using the integrated import/export feature, which now has been completely rewritten with v4.20 with the following benefits:

  • Reduced RAM usage by over 90% without sacrificing import speed when using CSV
  • Better error correction/handling for wonky CSV files
  • No more incomplete data – if the import fails at any point, no data will be written
  • Added geocoding cache in order to help prevent reaching geocoding limits on repetive imports (of the same, faulty file for example)

add zoom option to location finder

The location finder has also been improved. You will find a new “zoom” option on the map edit page (with “advanced settings” enabled).

This feature is disabled by default. If you set a zoom level here, the map will zoom to this level when you look up a location without choosing a maximum distance.


add AJAX test to health check

On the tools page we enhanced the integrated plugin health check. Now also a check is performed if your AJAX endpoint (admin-ajax.php) works without any issues (as this is an issue raised often in support tickets). If you see an X here, please check if e.g. some security plugins or firewalls prevent access to /wp-admin/admin-ajax.php. Please note that this endpoint is not only needed by Maps Marker Pro but also for WordPress in general.

In addition, the result of the health check is now also shown on the Maps Marker Pro admin dashboard widget on the general WordPress dashboard:


add option to show marker to geocoding control

With v4.19 we added a geocoding control, which optionally can be added to your maps. With v4.20 we now also added an option to show a marker when zooming to the found location:

This marker is disabled by default and can be enabled and customized on the map edit page, tab “Controls” (with “advanced settings” enabled):


add marker shorthand for custom shortcode

Please see the Shortcode API reference for details.


add option spiderfyOnEveryZoom to marker clustering

The clustering feature has also been enhanced with this release: you can now enable the option to spiderify markers in a cluster on every zoom, instead of just on higher zoomlevels. You find this new option on the map edit page, Tab “Markers” (with “advanced settings” enabled):
