I just upgraded from 1.4.1 to 1.5 and it seems the site is broken now. I followed these steps:

1: Backed up /home/opensour/geeklog
2: Backed up /home/opensour/public_html
3: Copied new /geeklog contents to /home/opensour/geeklog
4: Copied new /public_html to /home/opensour/public_html
5: Copied original config.php to /home/opensour/geeklog
6: Copied original libcommon.php to /home/opensour/public_html
7: Loaded http://www.mysite.com/admin/instal/index.php
8: The installer did not locate db-config.php so I filled in the path manually as /home/opensour/geeklog
9: At the next stage the database settings were defaulted so I filled them in correctly

Going to the site now I get the error:

Fatal error: Call to undefined function COM_createImage() in /home/opensour/geeklog/plugins/staticpages/functions.inc on line 877

Any suggestions?

You need to use the lib-common.php file that comes with 1.5.0.
