[kconcepta]

Hi,
When i try to do a backup/restore of Odoo database I get the errors below:

1. "Could not get content /gantt_improvement/static/src/css/gantt.css defined in web.assets_backend"
2. "Could not get content /gantt_improvement/static/dhtmlxGantt/dhtmlxgantt.css defined in web.assets_backend"

anyone able to sort this?

@kconcepta Are you sure the module gantt_improvement is installed ? Try to uninstall it and reinstall it.
