This is a port / rewrite of a MapBBCode MOD for phpBB 3.1, which has a new extensions system. Well, they didn't change other files much.

1. Extract mapbbcode_ext.zip to your phpBB 3.1 installation under ext directory. E.g. to /var/www/sites/phpbb/ext/.
2. Open the admin panel, "Customize" -> "Manage extensions" and enable the "MapBBCode" extension.
3. Check that [map] bbcode works, and there is a "MapBBCode" administration panel in "Posting" tab.

If you want to use plugins or proprietary layers, like Google's, you'll have to modify two files inside ext/zverik/mapbbcode:

• adm/style/acp_mapbbcode.html
• styles/all/template/mapbbcode_init.html

After that you would have to clear all caches. For example, by cleaning the cache directory, or maybe clicking the "Purge the cache" button in the "General" tab of the admin panel.

GPLv2. Sorry.
