Completely stuck using Odoo Online Version 18.
While attempting to save a new Sales or Subscription Order, the system returns the above error message (full details below). I have cleared cache, history, disabled all extensions, then tried on three different browsers, and also on an iPad, and the Odoo official app on iPhone 16. All with the same results. Same thing logged in as another user.
Support cannot replicate what I am seeing.
Can anyone please help?
Thank you for this suggestion, it seems to have resolved my issue.
