I’ve had other reports of something similar this with the Topper Image, but no one has sent me a project file yet to look at it. I ask for information and people go silent, so I’ve had nothing whatsoever to go on.
This is one example:
Your particular report seems a little different to me if it is confirmed to be working on other instances of Alloy on the same server.
Just to close this off, for anyone else finding it. The issue was me!
I had some custom JS in the project, and did remove it from the project during trouble shooting, but it was still on the server, so had to rmeove it from there too. Once it was gone, everything is working.
Worth mentioning, even with the error being caused by the custom JS Safari worked fine, but Chrome didn’t.
