Thread:Project:Support desk/Table 'wikidb.knowledge archive' doesn't exist

Am new to using Mediawiki. I set it up on a local machine and it has been running good. Today when I went to Webmin and clicked on the database to make a back up I got the following error

SQL show index from `knowledge_archive` failed : Table 'wikidb.knowledge_archive' doesn't exist

Great! My question since it seems to be missing, just how do I correct it so I can make a backup? I am afraid to restart the mysql service as the service is running currently here is  some information about the mediawiki version and such.

Product 	Version

MediaWiki 	1.16.2

PHP 	       5.3.3 (apache2handler)

MySQL 	       5.1.42
