Ok... I've been a happy user of an installation which worked fined, and I saw no reason to upgrade. Now i thought - Well, let's give it a shot. So I backed up my database and installed the new upgrade. After fighting ½ an hour with getting a download, I completely erased all the old files and uploaded the brand new ones. Installation went well - until I uploaded the database.
Now it says:
Error in obtaining userdata
SQL Error : 1054 Unknown column 'user_login_tries' in 'field list'
SELECT user_id, username, user_password, user_active, user_level, user_login_tries, user_last_login_try FROM phpbb_v*****_users WHERE username = 'Peter Holmgren'
Line : 65
File : login.php
"Fine!", thought to myself, and downloaded the good old version I know so well, and re installed it again. And wouldn't you know? It works!
A wise man once said, "Never change a running system". I've just found out how right he was.
