Don't you have a file call editor.php inside your weathermap directory ?
Inside it you have to set the $ENABLED to true to be able to use the editor online.
Yes I do, but the way it is built, as long as the editor is loaded in the Cacti UI it doesn't care about wether $ENABLED is true or not to start with.
I don't quite remember now but, if you have a look at weathermap-cacti-plugin-editor.php file, it tells you what file is currently using (editor.php).
Yes, the editor itself is editor.php.
But I'm looking for a config file that's supposed to be present. Here's the relevant part from the manual:
Once you have weathermap itself working, continue onto the editor:
Copy the editor-config.php-dist file to editor-config.php. If you want to be able to pick data sources from your Cacti installation by name, edit the file and make sure that the line that sets $cacti_base is correct, and that the base URI below that is also correct for your Cacti installation (these two lines are marked CHANGE in the file).
Since version 0.98, you no longer need to edit the editor.php to enable it unless you want to use the editor outside of Cacti. Otherwise, you can edit existing maps by clicking on their name in the list of maps in the Cacti Manage..Weathermaps page, or by clicking the 'Weathermap Editor' link at the bottom of the page to create new maps or edit maps not currently being used.
You will need to have the Cacti permission 'Edit Weathermaps' to be able to do this.
