I removed "&nocount=y" from the address of the download image on the
tw.o homepage and this enabled it to display again after several days of
being missing. With the original image address, entered in my browser, I
got a system error at info.tw.o:
"The following error message was returned:
Unknown column 'comments_enabled' in 'field list'
Database is not currently up to date! Visit Tiki Installer to resolve
this issue. "
So probably someone should run info.tw.o/tiki-install.php.
