Upgrading Drupal

I finally upgraded from drupal 4.3 to drupal 4.7. Everything went fine except for a few things that I've noticed.

1. The modules page is no longer available
2. I am unable to access the page containing my primary and secondary links

Is there something that I could do to fix this?

Thanks

While attempting to upgrade from 4.6 to 4.7, the upgrade.php script returned the following mass of error messages. Does anyone have any ideas of how to overcome this??????

* user warning: Table 'contact' already exists query: CREATE TABLE contact ( subject varchar(255) NOT NULL default '', recipients longtext NOT NULL default '', reply longtext NOT NULL default '' ) in /home/peaceful/public_html/includes/database.mysql.inc on line 120.

After upgrade to new 4.7 from older 4.6, was able to overcome all except this issue which may be due to new features.

I have the entire website using https. All shows fine, the lock and all. I do use rewrite and edited .htaccess to have drupal as a folder. Never got an encryption warning with 4.6 so that was fine.

ON 4.7 if I go to the add content page or a page with new fancy features with Microsoft Internet Explorer I get a
"This page contains both secure and nonsecure items. Do you want to display the nonsecure items?"

While this dialog window is present, for example on the node/add/page
I don't see the triangle in front of ---File attachments--- nor do I see
the gray area under the textarea fields. If I click yes/no or X in the corner
I get same resulting page with the gray bar under textareas and the triangle in front
of ---File attachments--- indicating more collapsed info----

FIREFOX was not a picky and did not complain about both secure and non-secure...

It could be a browser problem interpreting the style or scripting? but unfortunately
many consumers use MSIE and because the website has private info, seeing a "nonsecure"
warning in dialog window is not a good thing for the call desk. So I really need to resolve this
operationally. Must be a new viewing feature tripping this?

Looking at the page source I see includes for css and javascript but no src calls for http,

This is perhaps a bizarre question to ask you guys but I'm not the most technically-minded and would just like a bit of advice here. I'd be very grateful if any of you could help.

At long last, enough contrib modules have been upgraded for 4.7 for me to upgrade my site. So far, so good - pretty-much everything seems to be working, and most little bugs I'm sure will be ironed out soon.
