Hi,

I am using odoo 14 community on an Ubuntu Server. I have no problems installing third party applications. However the problem I am facing is that whatever pos third party application I install, the custom buttons from the third party applications do not show on the POS at all. The settings and features of  the third party applications outside of the POS show with no problems but inside the POS  custom buttons do not show. I have tried this on Odoo 13 and faced the same problem. I also realized that if I try to install themes, menu buttons do not appear at all. It seems like whatever images or buttons there seems to be a problem with Odoo displaying it. Does anyone know what the problem might be. Thanks
