#5 0.1.13 activation gives errors

[Anonymous]

Ok, I had Gallery version 2.0-something, and I upgraded
to 2.1 full. During the upgrade, it said that Checkout,
CheckoutPaypal, and CheckoutEmail could not be updated
because they were old versions. So I went to the
official site, downloaded the newest versions, and
installed them. Then I continued the upgrade. It failed
on those modules, throwing some SQL errors. Then it was
giving me an "Upgrade" link on "Checkout", but it would
always throw an SQL error (and it insisted I had 0.1.12
when I had just uploaded 0.1.13).

So rather than try to debug it, I wiped the whole
database, deleted the gallery folder, and started a
fresh install. I installed everything just fine, then
uploaded the 3 Checkout modules. Now, when I try to
activate the module I get this error:

Notice: Undefined index: sidebarBlocks in
D:\websites\lavasend\gallery\modules\checkout\module.inc
on line 256

Notice: unserialize(): Argument is not a string in
D:\websites\lavasend\gallery\modules\checkout\module.inc
on line 256

Warning: Cannot modify header information - headers

in
D:\websites\lavasend\gallery\modules\core\classes\GalleryPhpVm.class
on line 124

So the gallery shows it as Activated, but the "Add to
cart" buttons don't show up unless I'm logged in as
administrator. I've already added the cart block to the
sidebar, so the "View Cart" thing shows up... But I
never see any "Add to cart" or "Add this album to cart"
links, and I've tried table view and list view.

Suggestions?
