How to add custom date format in Localization settings?


I want to add custom date format to list at localization settings. I added a row into tables data_formats and datatime_format, but it didn’t appear at the list.


I’m not sure if this is supported but it may help to clear the backend cache by loading /update?secret= as well clear the frontend data by clicking ‘Refresh data’ on Settings > Device Settings.

Still nothing. It must be not supported.

Is there an option to create a custom date format for invoices?

@david can you please advise?

you need to refresh the cache using /update?secret=secret

This works, using just “/update?secret=” doesn’t.
