CiviCRM Community Forums (archive)

I am upgrading civi from 2.0 to 2.1 following these instructions (http://wiki.civicrm.org/confluence/display/CRMDOC21/Upgrade+Joomla+Sites+to+2.1) and I made it all the way to the step where you go to this url to upgrade : http://<your_joomla_home>/administrator/components/com_civicrm/civicrm/install/upgrade.php?reset=1

When I went to the url to upgrade, I receive this error:

Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in /home/eeaoregon/mydomain/administrator/components/com_civicrm/civicrm/CRM/Core/BAO/Setting.php on line 127

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/eeaoregon/mydomain/administrator/components/com_civicrm/civicrm/CRM/Core/BAO/Setting.php on line 131
 
Sorry. A non-recoverable error has occurred.
Log file CiviCRM.log is not writable. Make sure files directory is writable.

When I went to the url the second time I get this error:

Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in /home/eeaoregon/mydomain/administrator/components/com_civicrm/civicrm/CRM/Core/BAO/Setting.php on line 127

Sorry. A non-recoverable error has occurred.
Database check failed - looks like you have already upgraded to the latest version (v2.1) of the database.

Thanks for any help!
