Upgrading Drupal

I upgraded to 4.6.6 yesterday, and since then, I can't get most of the modules I want to work, most importantly image module. If I put the folder back in, the modules section of Admin loads full of code. I have to delete the image module folder to be able to access that area of Admin.

I have similar troulbe with the Amazon module.

What am I missing/doing wrong? Thanks

Hello. I've been running a hacked and tweaked 4.6.3 for a while now, and now that my site is finally on the eve of launch, I want to upgrade to the current release.

So i just installed version 4.7 beta6 and there seems to be a change to the way teasers are displayed, namely there is a new <br class="clear-both"> above the links. This leaves me with a lot of space between my content and links which i don't want.

I checked the drupal.css file in the misc folder and noted that the style for this break is specified with a height of 0px. This doesn't seem to work on explorer or firefox. If i add line-height: 0px instead it looks ok on explorer but still doesn't work on firefox.

I want to hide navigation for anon users but it should be visible for auth users (user/1 -> I've only one registered user). I am using 4.7 beta 6. I read some patch updates, but they don't seem to be for the version that I'm using. Can some one please let me know, if what I want is possible and how?

Thank you very much,
Joseph

upgrading from 4.5.2 to 4.6.6, at the point I access update.php according
to the directions, I get "accessdenied to username@localhost" as though
the user and password were not being read from conf.php

Hi, everyone!
Please help me, I can't find the information how to pass from 4.6 to 4.7 version so that all the data in database stayed untouched, that I would be able to keep the design of my template, and I could use the new version of the tree menu ( primary/secondary links ). Does anyone know, which modules I should update? and if some new tables in the Database should be created?
Thank you for help!
