Upgrading Drupal

I don't think this is actually doing any harm, but it is sure making my modules page harder to navigate:

when trying to run an update on drupal 7 I get:

An AJAX HTTP request terminated abnormally. Debugging information follows. Path: http://nkts.org.uk/update.php?op=selection&token=gmOdUvl2PYO-j3gNc6ET8Jd... StatusText: ResponseText: ReadyState: 4

The update process was aborted prematurely while running update #7076 in system.module.

how do I fix this please?

I've recently updated core from 7.9 to 7.17. Things seem to be working correctly, except, all system generated links are no longer recognizing the correct base path. I have my install in a subdirectory so the base path is mydomain/subdirectory. No problems in 7.9, but now all system generated (including menu) links only render the top level/root (thus excluding 'subdirectory') as the base url. The htaccess file is working correctly (as is clean url's). And drupal is rendering the correct base_url when I test print the $base_url. Any ideas?

HI, I am in the process of upgrading my site from Drupal 6 to Drupal 7. I have now upgraded pathauto but just do not understand how to use it? The pattern for the path is to be written in another way than in Drupal 6 and I don't get it? I have searched for help both in dokumentation and here in the forum but I only find documentation regarding Drupal 6.
I want to create paths vocubalaryname/termname/nodetitle which in Drupal 6 was written [vocab-raw]/[term-raw]/[title-raw] but which tokens should I choose to get the same effect?

I've just upgraded a site from D6.26 to D7.16, with views version 7.x-3.5, and if I try to edit an existing view (e.g. frontpage) or create a new view, once I click save I get "The website encountered an unexpected error. Please try again later."
update.php did not report any errors during the upgrade.

Any ideas? (and any way to get better error data?)

I have both a live site and dev site hosted on a virtual private server [MediaTemple (dv)]
The live site is a secure domain which points to folder: /livesite
The dev site is a non-secure domain which points to folder: /devsite

How do I flip the live site to use the dev site?
