Upgrading Drupal

Hello,

I have deleted everything (except sites folder) and reuploaded twice. Can someone help me?

I have restored the site back to 7.15 because the update keeps getting back these errors after many times of trying to do this. I AM logged in as User #1.

When I run the update this happens:

I have a legacy D6 installation that I'm going to upgrade to D7, but I need to keep the D6 version running for a while as I also upgrade the server to PHP 5.4/MySQL 5.5. I've set up a testbed and moved a copy of the D6 site onto it to see if anything breaks. So far everything seems to work just fine with one exception: a custom search module that's the primary purpose of the site. The form elements all appear and function correctly, but for some reason the html text and css formatting around them don't print to the page. For example:

Upgrading both Drupal from 7.22 to 7.26 and PHP from 5.3 to 5.5 (on Ubuntu Server), Drupal login doesn't work (and no log errors was track). But, if I move Drupal on my local computer, with PHP 5.3, it works!

May it be the version of PHP with Drupal 7.26 or some extension? Is Drupal 7.24 compatible width PHP 5.5?!

Please, HELP!

Hello Drupal community!

I have searched for several days and not come up with a solution and am hoping someone might be able to help.

I have redesigned my website in durpal 7 (original website is in druapl 7). One of the major reasons for the redesign was to improve the structure of the URLs. I've used taxonomy to divide the site into three sections A, B and C.

current website structure, with all content falling under the articles banner:
website.com/articles/node-title

after running the update, none of my pages load, all show the same error:

Warning: require_once(/home/content/08/10110408/html/includes/common.inc) [function.require-once]: failed to open stream: No such file or directory in /home/content/08/10110408/html/includes/errors.inc on line 62

Fatal error: require_once() [function.require]: Failed opening required '/home/content/08/10110408/html/includes/common.inc' (include_path='.:/usr/local/php5_3/lib/php') in /home/content/08/10110408/html/includes/errors.inc on line 62

I keep getting an e-mail saying that I have an update to one of my modules. When I click on the link it takes me to the /admin/reports/updates page. I go through the steps of installing the update and when it gets to the /admin/update/ready page it gives me the following error message: "Fatal error: Class 'FileTransferLocal' not found in /home/gerbreown/drupal/modules/update/update.manager.inc on line 456"

This has happened a number of times.

Has anyone else experienced this problem?

Thanks.
