I'm using simple map 2.4.5 with WP 3.5, and when I activate the plugin, it breaks the WP menus functionality.
How to reproduce the error
1) Activate the plugin
2) Go to Appearance/Menus (in WP dashboard)
3) Try to move any menu to a different possition.
Result: It can't move.
4) De-Activate Plugin
5) Redo steps 2 and 3
Result: Menus can move again.
Could someone please tell me how can I fix this bug?
