Upgrading Drupal

Hi,
I had my site in D4.5 properly funcionning.
I migrated to another hosting. The MySQL changed from 4.1.2 to 5.0.45

Now, I cannot go further than the user page after the login. After that, my admin user get "You are not allowed to acces this content", what ever admin page I choose.

Is theere a special step when importing the DB from 4 into the 5 version of MySQL?
I have checked that all tables have been copied.
The site works well for anonymous users.

What else should I be checking?

Thanks for your help.

I am currently running Drupal 5.1. My website host Hostgator is moving to PHP 5. Please help

What is the reasoning for PHP 4.3.5 being required on Drupal 5.7, but not Drupal 5.2. I have just upgraded a site from Drupal 5.2, and now the status report required that I upgrade to PHP 4.3.5. However, the system set up by the Network Admin does not have any updates for PHP past 4.3.4. Does someone know the reasoning for this requirement? If it only relates to a possible problem that will in no way affect me, then I might move on without worrying about updating PHP. Thanks for any help.

hello

a short question: can i update directly from 5.1 to 5.7? or do i have to go through all the other updates between them?

thanks and greetings momper

I have a strange problem:

I have upgraded from 5.5 to 5.7 and everything seems to be OK. All my pages are showing, I can log in as my admin user and go to the admin pages, see the logs, check the status of the site.

Hi Folks,

Have spent tons of time on this with no luck so I'm at your mercy now :)
