Upgrading Drupal

I just upgraded from 4.6 to 6.16, that went decently smooth, but now i have 137 tables in my database!
I'm sure its save to drop half of them, but which? That's the question I seek answers for in this thread.

I'm a seasoned Web Developer just as much as I am in Drupal. I came on-board around -- oh I think it was the beginning of 2008. I'm looking to find out from a seasoned developer what has changed since around 2008 as far as major core changes. Please don't refer me to the changelog. I've already taken a gander at that. I just want some details about the major changes that need to be noted. Your answer is much appreciated.

Hi,

Im having different search results.
Sometime when i use a keyword (qwic), the results are correct, but when using a different keyword (giant), i get results that dont even have the search keyword in them. And the result contains all nodes on the site.

I have cleared search tables, re-indexed the site, but problem remains.

Any help/ideas ? Maybe on what can cause this ?

I recently upgraded from drupal 5.7 to 6.16

Hello!

I´ve got a pretty odd problem with my drupal site.

In the body section, (when creating for example a blog entry), it seems to be a small web browser window?!
The area where you are supposed to write the text is fully covered by this. At first I thought it was a picture but now I know that it´s a web browser window.

So, have anyone of you ever heard of something like this? Maybe a solution?

Aye, thanks for reading!

Well things are pretty well fouled up now. I tried upgrading nodewords and something wrong. Can anyone give me a hint of what I might try.

Hi, after having applied the last security updates of Drupal and i18n, i'm getting this warning error:
Unknown column i.format drupal...

There is an explanation here: http://drupal.org/node/736252, but I can't figure out how to correct this (the second post of that page says it all: the README.txt of the i18n module does not contain a section 4, neither the Drupal readme.)

Thank you in advance for your help.
