Category: Installation and setup
No. The WordPress.com hosted platform does not allow to install additional plugins, making it impossible to install Maps Marker Pro. Maps Marker Pro only works on self-hosted WordPress installations.
Yes, installing Maps Marker Pro on a WordPress MultiSite installation is possible. Just keep in mind, that the license model is domain based, so if you are using subdomains for your multisite installation you need to activate a license per domain. If your subsites are accessible on subdirectories on your main domain though, only the main site has to be activated.
You will find detailled information and a tool tool to propagate your license to your subsites on the license settings page.
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!
