Container stops working

Container stops working unless I check “Freeze URI”, theURL sticks to the .html path
Any idea?

What do you mean by “Container”? From the Collections extra?
What exactly does “stop working” mean? In the manager, on the frontend?

Also not sure what you mean by that. Please be more specific.

Check the system setting “container_suffix”. Is it set to a slash?

You are right, it was the “container_suffix” setting. Thanks !
