Upgrading Drupal

I have just finished updating drupal core from 7.22 to 7.23. I have also updated a number of my modules including:
the security patch for entity api (7.x-1.2)
Content Access 7.x-1.2-beta2
Features Tools 7.x-1.6
webform 7.x-3.19

Now when I visit my available updates page (after running update.php of course) I see that most of the modules have been updated as has core.

However I still see the security update warning for entity api as well as update available status for the rest of the modules listed above.

More of an "update" than an "upgrade" but this seemed to be the closest fit.

I was working in Drupal 7.22 (I do use Acquia Drupal Desktop Control Panel, but use current Drupal Core), and was receiving the notification that I needed to update to Drupal 7.23. Being fairly new and learning, I first looked for the how-to in Drupal.org for best practices for updating Drupal Core. Couldn't really find something for newbies like me, with good old step by step planning, so I went to my fallback and pulled up the videos on lynda.com Drupal 7 essential training, that did have step by step instructions on updating to a new version.

First I installed the module migrate and backup. I created a backup of the site, I also copied the site folder into a backup folder.

Then, as instructed in the video, I downloaded and extracted drupal 7.23 to my folder...deleted the site folder, then copied my old site folder to the 7.23 folder. Then I renamed the old site folder "old site folder" and then I renamed 7.23 with the site name. Opened the site, and the first page came up fine...but if I click on ANYTHING, log out, log in, modules, structure--any kind of link at all, I get the 403 Forbidden error and it says "You don't have permission to access / on this server."

I tried resetting it to the old file, and now I can't even get into the first page.

I started with 4, then 5 then 6. Now I am working with 7.x. I could not update some old 6.15 sites to 7.x and had to start ALL over. Before I get overly committed to to 7.x, I wonder if starting with 8 would be a better idea.

Mainly concerned about updating database - that was the problem with upgrading before.

Thoughts?

Thanks.

I get the following messages on my Drupal websites:

Just tried upgrading to the latest version of Drupal (7.23) from an earlier Drupal version - pretty sure it was at least Drupal 7.2. Not had a problem before, however this upgrade has presented the following error. Any advice?

I have replaced the actual URL of the site with 'sitename' in the error beneath.

Parse error: syntax error, unexpected T_CLASS in /homez.744/sitename/www/includes/bootstrap.inc on line 306

Very grateful for any help.

I'm upgrading a Drupal 6.28 site to Drupal 7.22.

In D6, the Taxonomy Menu module manages menus for a few vocabularies. When you add a new vocab item, the menu automatically refreshes with the new item.

In D7, the menus initially do not show. After going through the upgrade process for Taxonomy Menu, the menus still do not show. If I add a new vocab item, nothing apparently happens. If I select "Select to rebuild the menu on submit." still nothing apparently happens. It also says "The Taxonomy Menu menu-topics (or-whatever-name) has been updated." In D6 and in D7, the Menu location is set to "= DISABLED =".

If I change the Menu location to something from the select list, with "Select to rebuild the menu on submit." selected, the screen fills with errors. Two warnings each for each term in the vocabulary. and then at the end a final error because fields being inserted are NULL. (See sample below)

The other thing is that even though I am using 7.x-1.1 of the Taxonomy Menu module, its README.txt file says this:
"(README.txt: 13th of April 2009, Version 6.x-2.3, indytechcook + ksc)"
and its UPGRADE.txt file says this:
"Upgrading from 6.1 => 6.2"

If all else fails, what do I need to delete in the database to remove everything associated with this module, so I can start from scratch?
