Upgrade to rc2 from rc1 breaks site.

Same here.

I am having the same problem.

Same here, BUT a fresh install, NOT an upgrade.

Remove the lines in the files below that have a "-" sign before them. These lines are all near the top of the file. This was created as a diff, but I've removed the context in case some of the people needing this help aren't familiar with reading patch files.
acquia_marina/block.tpl.php:

- <<<<<<< HEAD

acquia_marina/page.tpl.php:

- <<<<<<< HEAD
- =======
- // $Id$
- ?>
- >>>>>>> Updated theme files to Drupal 7 version

Same problem, deleted extra gobbledy-gook, but other errors are appearing as well.

I made the changes. Thanks.

But there still seems to be a major problem. I have three blocks in the content region that should appear vertically, one after another. Instead, they are displayed side by side with most of each block's content overlapped with the next one.

Am I missing something?

The CSS between rc1 and rc2 changed significantly. And rc1 was very different that 6.x version. I am not having a column problem, but all my tabs and curved corners had to be adjusted for rc1 (which uses corner radius's) and then in rc2 they went back to the image-way of doing it. I would check your CSS.

Thanks for the feedback.

As a newbe, I wouldn't know where to start. I installed Fusion Core (7.x-1.0-alpha1), Skinr (7.x-2.x-dev) and Acquia Marina (7.x-1.0-rc2).

I did NOT make any changes to the css so I should be at the default for everything. Oh, I did make some minor settings choices for Acquia Marina; but only from the menus.

A mistake was made when releasing RC2 and bad code was pushed here to drupal.org. An RC3 version is now available which is basically RC2 but not bust-o, with a few small organizational changes to the available skins as well.

Sorry for the trouble everyone.

I deleted RC2 and installed RC3.

I am still getting following error:

Notice: Undefined variable: grid_width in function include() (line: 15 in file /home/users/svtliberec/example.com/web/sites/all/themes/acquia_marina/page.tpl.php).
Notice: Undefined variable: grid_width in function include() (line: 55 in file/home/users/svtliberec/example.com/web/sites/all/themes/acquia_marina/page.tpl.php).

The theme does not seem to be usable.

@MPeli, did you install the fusion base theme?

I did not. Sorry.

The Fusion base theme and Skinr are required

Everything is working now. Thank you for your time.
