Upgrading Drupal

I upgraded from 5.2 to 5.7 and all is fine, except my forum, which no longer shows posts. I followed some advice, and parsed some php code to determine if it was reading the correct MySQL table, and it appears that it is not. But, I did not know how to fix it. Problem is, I cannot even find that thread now!

Currently the forum is offline.

If anyone knows how to fix this problem, which I believe is related to Drupal looking up the incorrect table in the database, please let me know how to fix it!

Cheers

Jon.

Help

I have looked at the drupal site, and though there is simular problems, I cant find one which Match

I get the following but with "access denied" page and no way to log in.

Warning: Unknown column 'serialized' in 'field list' query: SELECT data, created, headers, expire, serialized FROM cache WHERE cid = 'variables' in /home/riyadhro/public_html/includes/database.mysql.inc on line 128

I check the database and the column is in the table.

I am running on Siteground and used the Fatastico upgrade.

I've got an old site running 4.7 and I'm moving to a 6.1 site. I'm not interested in saving anything but the user information and the profile information, but these two are critical. I was hoping I could just dump the appropriate tables and then import them into the 6.1 site. Is that possible? Is there a different/better way?

I have a couple of problems. I have a custom drupal site. I think i know what that means now. My designer has gone on to bigger and better things ( i am not sure if it is temporarily or terminally).

Anyway, the problem is that the front page says you can't access site or something to that effect (actually you can).

However in order to stop scaring people away i was wondering how i can move it?

i need to add some functions like a rating system and better image galleries and a better video upload module and classified module. Should i stick with 4.7 or try to upgrade.? my site is yourgolfspace.com any advice would be very helpful...

how to add wiki to drupal?
thanks
