[Mediawiki-l] Upgrading from 1.4.7 to 1.6.7 - issue running update.php

[khuffman at NGS.ORG]

Hi, I've downloaded MediaWiki 1.6.7, backed up my database and its 
content, uploaded all the new files preserving the files that the Upgrade 
file recommends in the newest release but have run into a problem. My Web 
hoster "does not offer telnet or SSH access to the servers due to the 
nature of shared hosting. This could result in breach of data protection, 
and privacy laws." Is there an alternative option for upgrading? Thank 
you, Karen
