[TYPO3-dev] Problems with update from 3.8.0 to 4 beta 3

[Andreas Balzer]

Hi!
I just installed a testserver with the apache typo3 3.8.1 package on my 
local machine. After that, i deleted all database tables from typo3 
3.8.1 and deleted the whole typo3 folder. Then i copied my 
productionserver files and databases to the server on my computer. 
(production server has 3.8.0) After that i tested if everything works 
fine. It did.. Then i just copied the Typo3 4 beta 3 source package on 
my 3.8.0 testserver. Everything went wrong :)

Well, first of all, the install script always asks me for a new 
password. The other things are fine there. I looked in the update 
section and was surprised, that it wants to emulate 3.8.1 and not 3.8.0. 
  (you know, i just removed everything from 3.8.1.. It should be 3.8.0 
now..)

Ok.. I wondered and wanted to look into the FE.. Result: Database error

"Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in C:\apache\htdocs\contents\t3lib\class.t3lib_db.php on 
line 796"

Ok.. hm.. what could i do? I first thought that i could do something in 
the BE.. So i opened that, but there the same error occurs not once, but 
5 times on nearly every main page :-/

By time i noticed, that every Typo3 BE pagetree has some php database 
errors more. Several functions that get invalid MySQL result resources..

Well, i don't know what that means, because with my database everything 
should be fine.

I also tried to recopy all the files, but that did not work either.

So my questions:
What have i done wrong?
What should i do?
	Wait for help
	Go to other lists and ask there
	Write a bug report
	Try everything again
	Confront my head with the next wall :)

You have one joker.. ;)
