I’m a newbie, but a valid reason for me to be able to keep the database smaller is when you want to ex/import. My database is over 2 Mb is size and it could be that I’m doing something wrong, but due to my provider or due to PHP limitations, I’m only allowed to import files no bigger than 2048Kb. So if I have to do an import, I have to do that table for table or hack into my .sql files.
It seems you have solved the problem!? Would you mind telling us how?
Had the same problem. My wordpress files are in a subdirectory of my domain, but the index.php is in de root of my domain. So after the upgrade in index.php I had to change:
require(‘./wp-blog-header.php’);
into
require(‘SUBDIRNAME/wp-blog-header.php’);
Perhaps this helps!?
