Hi,

Ensure that you have assigned the image to the root menu, that is the menu shown in the main screen. To ensure cache is not causing any sort of issues, check in a new db and in a private window.

          web_icon="base,static/description/modules.png" groups="base.group_system"/>

Also ensure module is upgraded in the db, after adding the change and no update attribute is not set.


Thanks

You should restart your odor server. You have several other posts showing you how to do that. It is a different process depending on your installation type.

Also see if the module has an icon for the app in the records.

Hope this helps.

I'm still new to Odoo myself, but I ran into this before but it has been a while since I did it.  I believe what I did was activate developer mode by going to settings and scrolling to the bottom and clicking "Activate the developer mode".

Then, click the little bug icon in the top right of the screen and click "Regenerate Assets Bundles".  I believe what is happening is the style sheets and assets are cached and this makes Odoo refresh them.
