Dear Armin,
After 2 of my websites had updated to Wordpress 5.4 the lightbox plugin stopped reacting.
I tried to downgrade to the previous versions of WP, but strangely it didn't help.
I'm not using the latest Laytheme and Lightbox versions, but everything worked just fine until couple of days ago...
I would like to upgrade to the newest version of Laytheme, but I'm using a child-theme, which header and functions files don't work with the version...
Is it possible somehow update the child-theme so it will work with the newest version?
I don't want to switch from it, because then all the customization settings will get lost.....
Thanks a lot,
Sasha
