Hello @friskiu2,
Thank you for sharing your issue.
Do you have a custom field with a “Date” type?
If yes, you could try opening up a subscription form, open “Fields” tab, modify the date custom field, select a different format for the type of date and save settings.
Without having direct access to the site it’s difficult to tell, but I suspect you may have a date type with an unsupported format.
Changing the date type of that particular custom field to a supported one should fix the issue.
Let us know how it goes.
Best regards,
MailPoet team.
Thanks,
yes, a subscription form imported from Mailpoet2 had a custom date field requiring yy, mm, dd. Changed to yy, mm.
