Hi there,

Please share your PHP version by editing the original post?

I can replicate this on Mautbox, I’ll see if it is already raised on Github as a bug.


Thanks for that.
I use PHP Version 7.3.20
I noticed that the issue also when using your demo platform.

Kind regards,

Thanks for taking the time to let us know about it!


Just added this on Github but in case other folk are needing a workaround, this issue happens with image slots, you can add an image to a text slot without having this problem. So that might be a viable workaround until we get this addressed :slight_smile:
