Last update problem

Hi guys I just updated wordpress from version 6 to 8, and my website crashed due to plug in error with participant database… can a kind hearted out there plz help??? Urgent & desperate!

Displaying the published date rather than the modified date is default WordPress behaviour. Are you writing your own theme? If so, you could do something like:
echo get_the_modified_date();
instead of:
echo get_the_date();
