New Bug Encountered: Workflow Emails are NOT being sent as of 2 days ago

[James_McFarlane]

Hi as of monday of this week emails are not been sent. We have a workflow that gets triggered when an order is updated. Looking at the log it states the following but we have not made any changes to the app.
The error stated in the log is:

“Errors”: “Error: Workflow rule ‘Email Order’ action ‘Save a copy’ Body template. Expression ‘[TotalLinea]’ is invalid due to: Unable to find column ‘TotalLinea’, did you mean ‘TotalOrden’?.”,
