Hey David,

If it's a production environment, you can backup the database first and then follow the below steps.

1. Uninstall the enterprise modules (it might not work in some cases but you may try with it)

2. Remove the enterprise modules path from odoo.conf file

3. Restart the odoo service

4. log in to the database

Looking to your traceback error, upgrade the web module after you have followed the above steps.

Thank you!
