Upgrading Drupal

Hi,

I'm using version 7.8 and have gotten notification that a security update for the Drupal core is available. Checking the available updates page shows that, yes, core version 7.8 is currently installed and is recommending update to version 7.12 ?! I've been using Drupal off and on for years and have updated several installs, major releases, etc. (marvelous program, btw, it has always seemed to work as it should); but I've not had an occasion where the recommended update was a lower version number that the version currently installed.

I've searched the forums re this but am not finding an answer … I have a question about upgrading. I'm doing the upgrade to 7.12. I am following the instructions in upgrade.txt. I put the site in maintenance mode and follow the instructions to "Remove all old core files and directories, except for the 'sites' directory and any custom files you added elsewhere". But as the files are being deleted and I access the site as a non admin user from a browser I don't see the maintenance mode page, but rather an apache file listing page.

I've just upgraded to 7.12 and found that the Menu Block module now does not work. Is anyone else having this issue?

I am using ubercart module. I want that all product images of a product display in lightbox with scroll. Till now i am able to show my product images in lightbox but not able to show all images of a single product in lightbox with scroll.

I just upgraded Drupal for a beta site that I am working on. I get this error now on the home page and can't get past it. When I comment out those lines, all of my custom colors are gone. I am using the Pixture_Reloaded theme if that helps. Is there a reason that this error is happening, and can someone help me fix it? My custom colors actually worked for a little while and I don't know what I did. I am very new at Drupal and CiviCRM so it is quite possible that I messed something up. I have deleted the files and replaced them multiple times, but this error just keeps happening.
