Upgrading Drupal

I started with 6.6 working fine -- I've downloaded upgrades and installed them several times (tried both 6.7 and 6.8). I think I followed all the steps (went offline; saved DB; saved Sites, Files, ini.php; disabled all modules but Core/Required; deleted 6.6. files; unzipped 6.7/6.8 into same place; copied back old Sites, Files, ini.php; ran install.php). With modules enabled and back online, the site runs well, BUT...

"/reports/updates" stills shows "Security update required!" and Core - required (under /build/modules) shows all elements are still 6.6.

Hi

Is that a good idea?
What are the main benefits?

What are the main differences?
Is the 5.12 stable like the old 4.7.11 ?

Thanks

I have updated Drupal 6.7 to 6.8 and get this error Fatal error: Call to undefined function user_current_to_arg() in /hermes/web06/b684/pow.cblondeel/htdocs/drupal/includes/menu.inc on line 599

Please help me with this!

It seems necessary to step through DRUPAL-5-13 to DRUPAL-5-14. Is this correct (I will be trying soon myself, and will report back here)

I've recently upgraded my page from Drupal 5.x to Drupal 6.x
Many times (not all times) after making some of these clicks:

* edit content
* save edited content
* go to site search
* delete content

my click is automaticaly redirected to one and same page (in my case www.site.si/node/6843).
I've deleted that page, but it still goes to the same URL adress (node/6843), just that it says to me: Page not found.

Hi all,

I've update the Drupal several times in the past with no problems. However, I am now faced with the following error:
Fatal error: Unsupported operand types in /home/dstodd/gtagencies.com/gta-3/includes/common.inc on line 1539

Any ideas or clues on how to resolve this?
