Hi

Do you have any errors and exceptions in the eventlog?

If you try with developer tools do you get an exception?

Please post and we can have a look.

We have previously created a copy of an existing language layer, which was shortly thereafter deleted. Now when attempting to make a new copy the error persist.
Could this potentially cause the error?

This is the log:
