The first two files need to be verified to be present (most likely the config.ceon_canonical.php file is missing or not named to support loading) and/or there is either an override in includes/init_includes/overrides that prevents using the associated/necessary notifier or the file is possibly not up-to-date to the Zen Cart 1.5.5 version or better (based on notes in the observers file).[/FONT]

Happy New Year and best wishes for 2020, MC, health you and the other guru of the forem I do not know how we would do, that to tell you that you are very strong. You put me in the right track I had a residue in init_includes / overreides / init_canonical.php which probably came from USU which was installed before Ceon Uri Mapping I just had to delete this file and Ceon Uri is set to work as it should.
Thank you so much.

The template is ########## from themeforest, I have had a lot of problems with it since the first day, but now with the update the problems have started again, I hope to solve them with all of you.
