Update about "Change color for date field"

[scalisto]

Hey there

It's about this post: https://forum.espocrm.com/forum/deve...for-date-field

I'm trying to implemet this idea in my EspoCRM (Version 7.1.5), but when I put the code there, my espo just crash ("Error404" or something).

Maybe it's because the code is now incompatible with latest versions.

Do you have any idea or update about this?
Thanks in advance
