Custom module is loaded on Odoo 10 enterprise and works well.
Icon file is "moduleName"/static/description/icon.png (5kB png file)
Icon appear well on Apps module (use to install and update module). So it existing and is a right format.
But icon on main Odoo launcher view doesn't appear. A "standard" icon replace the right icon (a box with exclamation mark).
Any idea to view the module icon on Odoo main view ?
