Thanks, I'll do the template switch and test when there are less people on the website. Probably 10 hours later.

As for the URL rewrite, I think there is something like that set up at the server, I'll try to describe it:

The ZC store is installed in, say, user/public_html/dummydir but the shop URL is 2c dot hk instead of 2c dot hk/dummydir. This is something that I asked the host company to change for me.

Does that make sense? Sorry I'm not very familiar with server stuff...

Thanks!
