Further to the above issue, apparently there is a compatability issue with crazydomains.com.au’s servers and the Fantastico WordPress install. Unless and until they can resolve it, every WordPress install will need the fix to allow you to see the permalinks options.
The fix is even simpler than indicated above – it’s simply a matter of creating a php.ini file. I.E. a new, blank file.
The tech support guy created mine in the www\wp-admin\ directory, which you can easily access via an FTP client.
Not sure if this applies to anything other than the specific problem with crazydomains.com.au though…
Cheers.
