Upgrading Drupal

Hi, I'm getting this problem after I make a comment or create some content or deleting content or doing something:

Warning: pg_query() [function.pg-query]: Query failed: ERROR: secuencia de bytes no v�lida para codificaci�n �UTF8�: 0xe16d65 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". in /home/www/drupal/includes/database.pgsql.inc on line 125

Not sure what's going on, but I can't log in anymore as the administrator or any other user. I've done several other upgrades over the past year and never had the problem before.

I logged in as the admin user. Then I installed 4.7.6 in a new directory and copied my settings and theme files. I use several extra modules which are all in modules/contrib/ so I copied that directory in too. Then I ran the update.php script which worked, but didn't seem to do any database updates.

After that I browsed around a little, then logged out. But after that I can't log in again.

Hi,

I've upgraded to 5.1 from 4.7.4, and found that all of my menu items are now duplicated (administer, administer, site building, site building, block, block... etc.) . I can't even remove / disable the duplicates.

I'm using i18n, frontpage, OG, gmap, location, and event. I upgraded all these properly to 5.1.

Where can I begin to look for clues?

Thanks a lot,

s.

Hello everyone,

What's happening with my modules when I upgrade drupal to 5.1 as for as I know, following modules doesn't exist on 5.1 !!

taxonomy_browser
user_list
vote_up_down
banner

I need them all, or at least alternatives that work as good.

Thanks in advance!

I'm looking to move one of my sites to a different host that I have a 5.1 multisite install running on.

The site is currently on 4.7.2 so would I be best off upgrading step by step to 4.7.6 then to 5.0 and finally to 5.1 on the existing host before I move to the new host? Or could I move to the new host and shove the database directly into the 5.1 multisite?
