Topic on Extension talk:AdvancedMeta

I want to uninstall this extension and eliminate all tables, could you tell me how to do that?

To uninstall this extension you would just need to remove the following line from your LocalSettings.php:

wfLoadExtension( 'AdvancedMeta' );

The table name, that is created by this extension is "ext_meta" There is no need to delete the table as it is not used anywhere else. To remove it manually, you would have to execute a SQL statement
