Map Icons Collection now hosted on

The Map Icons Collection is a set of more than 700 free icons to use as placemarks for your POI (Point of Interests) locations on your maps. The project was originally created by Nicolas Mollet and thanks to many contributors it has become a central ressource for free map icons on the internet over the years:


Leaflet Maps Marker respectively Maps Marker Pro has also been configured to work out of the box with those icons (you can even use the integrated upload feature to easily enhance the default icon set shipped with the plugins).

Unfortunately the Map Icons Collection suffered many server issues lately. In the end the former hosting provider decided to block the website as they considered the usage was against their hosting policy (more details here).

In order to help Nicolas and to deliver a more reliable hosting for all users of the Map Icons Collections (including Leaflet Maps Marker respectively Maps Marker Pro users), I agreed with him to host the project website on (thx to my hosting provider for quickly helping out here!)

The project rules and usage conditions of the Map Icons Collection will not be changed through this hoster change: Nicolas will continue to lead the project and icons are still available under the Creative Commons 3.0 BY-SA license.

show warning message in dynamic changelog if server uses outdated and potentially insecure PHP version (<5.4)

Many servers hosting WordPress still use old PHP versions (which is not directly an issue for Maps Marker Pro as the minimum requirement is PHP 5.2), but as the support for PHP 5.3 was discontinued recently, still using a version below 5.4 is potentially insecure for your whole site and an update to 5.4 (or better even higher) is highly recommended.

To address this issue, a new project called by Coen Jacobs was started, with the aim to make end users aware of this issue.

To support this project, Leaflet Maps Marker respectively Maps Marker Pro now displays a warning message in the dynamic changelog section if you are using a PHP version below 5.4 with details on how to upgrade respectively what to tell your hoster, if you are not managing your server by yourself:

  • improved sanitising of GeoJSON, GeoRSS, KML, Wikitude API input parameters


  • PHP undefined index warnings when adding new recent marker widget
