I have done a migration to our company's SharePoint from 2013 to 2019.
Everything is working as intended except blog posts date function. At the moment whatever I do the publishing date seems to be 30.12 1899 when user views the blog post:
The issue seems to be in the display form or SharePoint settings? Because the dates are working normally in the blog listing and everywhere else in the SharePoint Environment.
I have also re-created the blog site from scratch and still the same issue.
Regional settings are also correctly inputted.
Any idea what causes this?
