Upgrading Drupal

Was converting a custom module made in drupal 6 to work in the site upgraded to drupal 7 followed all the steps in (http://www.slideshare.net/Phase2Technology/taking-your-module-from-drupa...) , the module doesn't seem to work below is the whole upgraded code I suspect the " convert this statement to the D7 database API syntax" part any help highly appreciated .

Hi,

I was upgrading my site to 7.28 and when I was done, I got the following error:

Fatal error: require_once(): Failed opening required '/home2/tennis/public_html/includes/modules/system/system.queue.inc' (include_path='.:/opt/php54/lib/php') in /home2/tennis/public_html/includes/bootstrap.inc on line 2811

Taking a look at the php, I knew that I was over my head. Can anyone offer guidance as to what I should do? I've searched for an answer online and wasn't able to find one.

Thanks for any assistance you can provide.

Hello,

These are the steps I follow to update Drupal. Do we have any drush experts on this forum? I'd like to confirm my steps are correct (and safe).

To update Drupal core from one minor release to another, I put the site in maintenance mode and execute the following command:

// See https://drupal.org/taxonomy/term/34882
$drush pm-update projects drupal-7.28

***

To update a single module , I put the site in maintenance mode and...

I recently updated from 7.26 to 7.28. At the update page, drupal issued this warning:

PHP register globals Enabled ('1')
register_globals is enabled. Drupal requires this configuration directive to be disabled. Your site may not be secure when register_globals is enabled. The PHP manual has instructions for how to change configuration settings.

php.ini has had register_globals turned off now.

This is the first time I've ever had an issue with the update routine.

Starting from 7.26, moving to 7.28, at update.php after hitting the Continue button, it just spins the page's loading icon forever. It just did it for several hours. I have no idea what action to take at this point. Hosting is on a shared server, linux.

A while ago, a problem popped up on my site. When I open update.php to perform a database update after a module update, it redirects to update.php?op=info, the page that indicates you have to create a backup and put your site in maintenance mode. When I click the 'Continue' button, nothing happens. The browser indicates it is loading, but the same page remains visible. The loading never stops, and the page remains the same.
