ISP: "Your changes cannot be saved " and no files are created

[tom]

I've created an new user and a new web. By trying to create an other co-domain I got this message:
Your changes cannot be saved because this item is currently being updated. Please try again later.
I've tried to save it several times but nothing happend.

Even no directorys and files for the new user are created.:confused:

What's wrong?

This are no faults or errors. The system locks the website while the config files where updtaed, otherwise it might corrupt your cnfig files.
