Frequently Asked Questions

I do not see plugin update notifications about new versions

The Maps Marker Pro plugin checks every 12 hours if a new version is available. You can also manually trigger the update check by going to Plugins and clicking on the link “Manually check for updates” next to “Maps Marker Pro”:

manual-update-check

If you do not see the link “Manually check for updates” or clicking on it does not show the latest version available, please proceed as follows:

Please first check if you are using v1.5.9 or v1.6. With v1.5.9 delivery of plugin updates via SSL was added to increase security. Unfortunately we found that although this features works fine, there might be issues on servers with outdated or incomplete SSL libraries. This can prevent your plugin to communicate with mapsmarker.com to check for new plugin updates.

To fix this, please manually update to the latest version, which includes a workaround for those servers. To manually update your plugin, please download the latest package from https://mapsmarker.com/download-pro, unzip the plugin package and copy the files from the unpacked folder /leaflet-maps-marker-pro/ to your server via FTP, overwritting all files and subdirectories in the directory youdomain.com/wp-content/plugins/leaflet-maps-marker-pro/

Please note: if you would uninstall and reinstall the plugin through the WordPress admin interface, all created maps would get deleted on uninstall, so please do a manual update via FTP if you have already created some maps!

If updating to the latest version did not solve the issue, please ask your hoster for help. There might be special security precautions preventing your server from communicating directly with https://www.mapsmarker.com (GET requests, Port 443)

It could also be that your server only allows direct connection through a proxy (you can verify this if you are not receiving any WordPress core or plugin updates). If this is the case, the proxy server has to be configured in wp-config.php (please ask your hoster for details about your proxy):

define('WP_PROXY_HOST', '192.168.xx.xxx');
define('WP_PROXY_PORT', '8080');
define('WP_PROXY_USERNAME', 'my_user_name');
define('WP_PROXY_PASSWORD', 'my_password');
define('WP_PROXY_BYPASS_HOSTS', 'localhost, www.example.com');

If you are not using a proxy, and still not see the that there is a new plugin version available, please install the debug bar plugin from https://wordpress.org/extend/plugins/debug-bar/. This plugin allows you to debug the communication to the update server on mapsmarker.com. After activation of this plugin, click on Debug in the admin bar and select PUC (leaflet-maps-marker-pro) from the sidebar. Afterwards you can check the communication with the update server by clicking on the buttons Request Info and Check now:

debug-bar-steps

If you or your hoster cannot help you with the information retrieved from the debug bar plugin either, please open a support ticket and we will be glad to help you solving your issue!

“Error: a new local license key could not be obtained.” is shown after license activation

connect-error

If you see the error above after trying to activate your license key on the license settings page, this means that your server could not connect to https://www.mapsmarker.com for the license validation.

Please ask your hoster for help here. There might be special security precautions preventing your server from communicating directly with https://www.mapsmarker.com (GET requests, Port 443)

define('WP_PROXY_PASSWORD', 'my_password');
define('WP_PROXY_BYPASS_HOSTS', 'localhost, www.example.com');

If that also does not help, please open a support ticket and we will be glad to help you solving your issue!

How can I rollback to an old version of Maps Marker Pro?

If you have any issues after an update, please open a support ticket. It the issue is severe and affecting all users, we will immediately start working on a hotfix which we make available as soon as possible (usually within 12-24 hours).

If you want to switch back to an old version until this fix is available, please download a former version from https://www.mapsmarker.com/updates-pro/archive/ and overwrite the plugin files on your server in the directory /wp-content/plugins/maps-marker-pro/ (v4+) or /wp-content/plugins/leaflet-maps-marker-pro/ (v3.1.1 or lower).

Please DO NOT uninstall and reinstall the plugin to rollback to an old version, as uninstalling the plugin will also delete all map data!

When saving a marker I get the error “a marker with the ID 0 does not exist!”

This FAQ is only valid for Maps Marker Pro v3.1.1 or lower:

Please check if the database tables needed for Maps Marker Pro have been created by logging into your database tool (usually phpmyadmin) and checking if the tables

  • wp_leafletmapsmarker_markers and
  • wp_leafletmapsmarker_layers

exist. If yes, please turn on WordPress debugging (by adding define(‘WP_DEBUG’, true); to wp-config.php), also have a look into the PHP error log if possible and open a support ticket with the logged results.

starting point when using Google Maps directions is incorrect

By default Google Maps is used as directions provider for the directions link in the map panel and for the directions link added to the popuptext of each marker.

If you entered an address for your location, this address will be used for directions starting point, if you only entered latitude and logitude coordinates (and address field is empty), these coordinates are used as starting point for directions.

If you notice that your starting point on the opened Google Maps is incorrect, than is because Google by default always calculates the directions by using car as preferred transport method. So the nearest place to your location that can be reached by car is taken as starting point automatically.

Unfortunately this cannot be fixed on Google Maps, as this is not a bug but a feature 😉 – anyway there are several ways to deal with this issue:

– if you only rely on walking directions, you can navigate to Settings / directions settings / Google Maps directions settings and check the checkbox “Walking directions”.

– if that is not an option for you (roads for cars will be ignored with this direction), please navigate to Settings / directions settings / general directions settings and set a different directions provider like bing maps, which takes exactly the coordinates of your location and does not change the starting point.

I would also like to use this form – is the source code available as open source?

Yes, actually I even built a WordPress plugin which you can download at http://wordpress.org/plugins/bitcoin-order-form-for-mapsmarkercom/ The code is also available on Github at https://github.com/robertharm/bitcoin-order-form

Please be aware that this plugin is customized for MapsMarker.com and has not options to customize the products in the backend. I shared the code for developers in order for them not having to re-invent the wheel but to only change some form parameters in the code if they want to use a customized version on their sites.

Can I add multiple GPX tracks to a map?

You can only add one GPX file to a map – if you want to show multiple GPX tracks on one map, you have to merge those files first – you can use the online tool at http://joewein.net/bike/gpxmerge/ for this purpose.

Since v4.0 though multiple tracks within one GPX files are also supported and can be selected by the related controlbox in the elevation chart:

Can I manually draw a GPX track on a map?

Since v4.3 we added polyline support which allows you to draw directly on your maps by using geometry layers like polylines, polygons, circles and rectangles.

You can use services like http://www.gpsvisualizer.com/draw/ which allow manual drawing of tracks and exporting the result as GPX file – which you can display on your maps with Maps Marker Pro.

If you are having issues with this tool, you can choose another one which supports GPX export – an overview of drawing tools is available at https://wiki.openstreetmap.org/wiki/Track_drawing_websites

Is this plugin compatible with WordPress multisite?

You need at least a single license to also install Maps Marker Pro on a WordPress multisite instance. The pro version even includes some additional admin tools which allows you to propagate the license key or custom settings to all subsites.
