I am making a QGIS plugin with QGIS 2.14.10
I use the reload plugin each time i want to update the plugin. But sometimes, when my plugin bug and i reload it, i get the icon twice in the toolbar and the first icon is off. It happen each first time that the plugin beug. And sometimes i get 3,4,5 same icon ...
How can i prevent this ?

unload(self)function. Do you have such code in your plugin and if so, could you edit your question to include this please as this could help potential answerers =) – Joseph Jan 20 '17 at 14:39
