Many errors on main page ( even for guests )

Just tried that, didn't change anything.

If I go into the block configuration, I get some additional errors:

Notice: Undefined property: stdClass::$aid_filter in _quotes_block_configure() (line 1107 of /sites/all/modules/quotes/quotes.module).
Notice: Undefined property: stdClass::$aid_filter in _quotes_block_configure() (line 1108 of /sites/all/modules/quotes/quotes.module).

I just did an uninstall and a complete re-install.

Attempting to save the 'block' settings page results in:

Notice: Undefined offset: 0 in quotes_block_view() (line 1005 of /sites/all/modules/quotes/quotes.module).
PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'vid' cannot be null: UPDATE {quotes_blocks} SET vid=:db_update_placeholder_0, cron_last=:db_update_placeholder_1 WHERE (bid = :db_condition_placeholder_0) ; Array ( [:db_update_placeholder_0] => [:db_update_placeholder_1] => 1356384049 [:db_condition_placeholder_0] => 1 ) in quotes_block_view() (line 1009 of /sites/all/modules/quotes/quotes.module).

Note: I have no quotes, and this breaks my entire page.

It seems the order must be:

1) Install module
2) Create at least 1 quote using the module / Save "General Settings"
3) Configure block

For the module to work properly.
