Hi,
I have just installed the virtual box version of erpnext 12 and upgraded to 13 to get the new interface. I can see lots of work has gone in and really enjoy the new look. But on the website I am getting this error. I tried adding the missing line in the website_settings doctype but still get the error, so presume its something more sinister in the code.
Any way to stop this message appearing to people? I mean the website works but a terrible big message saying DANGER Will Robinson or more exact
Failed to get method for command frappe.website.doctype.website_settings.website_settings.is_chat_enabled with module ‘frappe.website.doctype.website_settings.website_settings’ has no attribute ‘is_chat_enabled’
stops me wanting to migrate to production.
Full trace is
