I have copied lib_common.php many times to the site and the same error still exists.
Do I need to put the main config.php file somewhere different than it was in 1.4.1, or rename it
But I guess there isn't actually a problem: You will have to enter the database settings when you call up the install script. We don't read them from config.php (or db-config.php, on upgrades), as that would expose it to anyone who came by before you finished the installation and had a chance to remove the install script.
II can see no change in the database - no new table with configuration settings or anything like that but when upgrade fails it seems to put a marker in the database to say upgrade is complete and won't let the upgrade to be run again - most annoying.
Dirk, I'm getting the following error when I run the install/index.php:
