Upgrading Drupal

I've been searching for a couple hours and haven't found an answer. I've tried many search phrases, but I just don't seem to have a grasp on how to best search for what I'm trying to do.

I have over 30 individual (not multi-site) websites on Drupal 7,which I originally built and now maintain.

I have a Virtual Private Server dedicated only to sites I maintain with root access.

Hi there, i am new to drupal and am trying to figure out this updating system.

i am getting this error.

X There is a security update available for your version of Drupal. To ensure the security of your server, you should update immediately! See the available updates page for more information and to install your missing updates.
One or more problems were detected with your Drupal installation. Check the status report for more information.

Hello,
I'm using drupal 7.22 with Apache 2.2 , mysql 5.5 and PHP 5.3.
I'm having the error of WSOD, and when I enable the error message, it shows:
Fatal error: Call to undefined function views_get_enabled_views() in /var/www/drupal7/sites/all/modules/admin_menu/admin_menu.map.inc on line 150
It happens when I migrate the whole drupal to another system, or when I update the core to the recent released version, WHERE I enter the username and password to access the administration page ( /drupal-address/user).

Hello I upgraded Drupal c 5 to 7. Version 6 works correctly. When upgrading 6 7 I see the message:
taxonomy module
Update # 7001
• Failed: DatabaseSchemaObjectDoesNotExistException: Unable to rename term_data in taxonomy_term_data : Table term_data is not exists. function DatabaseSchema_mysql-> renameTable () (line 304 in file / www / ....... / www / htdocs / includes / database / mysql / schema.inc).

Hi,

After the latest security upgrade to 6.30 the ckeditor was missing toolbars.

I have tried countless things to get it working.

• uninstall/re-install both the module and the editor itself
• countless other editors have been tried but all have the same problem.
• permissions checked over and over
• checked all the files are correct when upgraded.

After the upgrade I did have these errors come up.....

Yesterday I upgraded the Edit module and today I get a blank page instead of the normal /user page. In the apache log I am getting the error:

[Thu Jan 23 11:38:26 2014] [error] [client 10.2.13.192] PHP Fatal error: Call to undefined function libraries_detect() in /web/extra/abbott/sites/all/modules/edit/edit.module on line 264

I am kind of a Drupal newbie and this is the first time I have run across a problem like this. How would I best proceed?
