When editing templates through the html editor on the website (in Odoo 13), the following warning is displayed on top of the editor:
If you edit and save this file, you will never receive updates from Odoo anymore unless you reset your customizations.
Now my question is: is there a way to reset customizations?
The reason I ask is I'm regularly running into errors when updating Odoo. These may be caused by templates that were modified manually, so I'd like to get rid of these manual changes if possible.
Ever get an answer to this?
Not really.
I think the cause of my issue was someone changed (a year or two prior) the inheritance-relationship between certain base views in a way that was not really OK. An update of Odoo then broke the situation for some reason.
As we were planning to replace our websites anyway, I fixed the situation in the following way:
* Uninstall the Website module
* Correct the view-relationships. ( by installing the same modules in a clean database and then comparing. A bit of a painstaking exercise)
* Reinstall the website module
I do not have all the details anymore.
As for the original question, I suspect there is no real process to reset customizations. They probably mean you should manually undo whatever changes were made to the base views.
