[Mediawiki-l] Upgrade Errors

[Ira Goldstein]

Hi all.

In preparation to move to 1.5.x, I'm upgrading our sites to 1.4.11 from 1.4.7.  While running the php update.php script I get the following errors:

Warning: Invalid argument supplied for foreach() in /home/wiki2/mediawiki/maintenance/commandLine.inc on line 161

Fatal error: Call to a member function on a non-object in /home/wiki2/mediawiki/includes/ObjectCache.php on line 409

Any suggestions would be appreciated.

Thanks
