Search for “DOB” in github code. It will be in a html file because calendar uses templating. On top of it they replicated the code for Day, Week and Month. You can fix one or all. Because the templates are “compiled”, you may have to clear cache before your change takes effect.
@stephenwaite I tried to do the fix on my working version. “”“My library/options.inc.php”"" has code in different line than in github, line 619, 620, and 693 instead of 628, 629, and 702 in github.
Also no “”“library/templates/address_list_display.php”"" and “”“src/Services/ContactService.php”"" pathways.
So is this fix for developing versions only or i have something broken.
