[CWB] Corpus installation problems after fresh install

[Graham Ranger -- UAPV]

Hello,
I went for a fresh install, after the previous problems, removing 
databases, etc. and installing the version on sourceforge 3.2.30.
I then tried to re-install a corpus. After installation I got the 
standard message "Design and insert a text-metadata table for this 
corpus", clicked on it, and got "The requested URL ...index.php was not 
found on this server."
I cannot see any obvious reasons for this (php version?). Any help, as 
ever, appreciated.
Best,
G. R.
