Got message from hkdnr saying that domain registration is done and ready. I therefore went to NetAdmin of Site5 to have it pointed to the subdirectory /emba. That pointing wasn't successful earlier today as it wasn't ready obviously. Anxiously tried that afterwards, too bad wasn't OK. Well another question for tech support.
The WP installation was re-done at a subdirectory. I said to engineering that it doesn't worth the hassle to find out why Fantastico was so mean about subdomain or subdirectory.
