Upgrading Drupal

Good morning!

This night I upgraded a site from Drupal 6.4 to 6.5. Everything went right... Everything but update.php.
Update.php returns this error:

"An unrecoverable error has occurred. You can find the error message below. It is advised to copy it to the clipboard for reference.
Ga verder naar de fout pagina"
Beneath that it shows all the source code of update.php in a red rectangle.

'Ga verder naar de fout pagina' (Dutch) means Go to the error page. When I click that it just goes back to the beginning page of update.php.

so no real issues at all, but for some reason my install kept sending me 'new updates available' emails every 5 minutes - there were in fact a couple of updates available, but i've set my install to email me once daily with such notifications...i simply removed the email from the field box and it stopped sending them, but it's kind of odd..

Hi,

Trying to run Update.php on Multi install drupal 6 after installing new version of some modules I sometimes get a blank page and sometimes this fatal error:

Fatal error: Call to undefined function phptemplate_get_ie_styles() in WEBSITE.com/themes/garland/maintenance-page.tpl.php on line 23

I finally managed to find this post:

After upgrading to 6.5 on my development site, I encountered several problems including the taxonomy access module causing a permissions issue and the dhtml module not working, both of which I posted in the appropriate areas. However additionally, I could not change my menus from the last state they were in before the upgrade, ie. menus were expanded and would not collapse regardless of what I did. I decided to go back to 6.4 until I can get these things sorted out.

Has anyone else had similar problems?

Thanks

I've managed to install Drupal 6.5 upgrade (I got an error in the SITE/ALL/FILES as not being writeable but seem to have fixed that by changign permissions)

I then tried to upgrade the DATE module and what I've ended up with is unable to get at the site building > modules page

I tried to enable date module and it said I had to enable Views but before I could I got a fatal error:

It just says

Fatal error: Call to a member function on a non-object in /home/buscfd/public_html/sites/all/modules/date/includes/date_api.views_default.inc on line 99

Is is safe to only overwrite with newer files when upgrading?

For example, the most recent file date in ver 5.10 is 08/03/2008. In ver 5.11 there are only 48 files with a date stamp more recent than 08/03/2008. Can I just overwrite those 48 files? I intend on using the following steps:
