this is a sqlite level error: http://www.sqlite.org/tclsqlite.html#authorizer
something registered an authorizer callback function which returns a SQLITE_DENY for VACUUM. your options are:
1. check the registered callback to see if you can aquire authorization
2. overide the callback (e.g. with a NULL callback or with one that returns SQLITE_IGNORE instead of SQLITE_DENY)
3. comment the VACUUM command in SQLite3Database.php
the last option is a hack and not recommended. it's not absolutely neccessary to vacuum. can you find out why there is authorization required? is there any other command that gets a SQLITE_DENY? if there is a good reason for the denial i can make vacuuming optional.
Silverstripe seems interesting and I would really like to get it running to play around with it some, but I keep having this error message during installation (see attached image).
I added the sqlite trunk module before installation and it showed as green in the list.
Did I miss something? Is sqlite3 broken or not and why is it failing to install?
