Hi!

But when I create and save a custom module I get this error: "Undefined constant "SLIDESHOWCK_MEDIA_URI" "

EDIT: It's any othe than Slideshow cK casusing this

Can you help me aut of this?

Thank you!

Hi
I have tested and I don't manage to create the problem by my side
what do you mean with "create and save a custom module" ?
I have tried a new Slideshow CK module, and a new Custom module, no message in the admin
CEd

I'm on Php 8 - maybe this causes the problem?

See my screencapture here:
