Wordpress MU: This file is too big. Files must be less than 1500 Kb in size

If you get the error above when you upload a file to a Wordpress MU blog, you need to change the maximum allowed upload file size. You can find this setting under “Site Admin … Options … Max upload file size”.

Unfortunately there is no option to change this value for existings blogs, but you can you change it directly in the database:

UPDATE `#YOURDATABASENAME#`.`wp_sitemeta` SET `meta_value` = '32000'
 WHERE (`wp_sitemeta`.`meta_value` = 1500)
 AND (`wp_sitemeta`.`meta_key` LIKE "fileupload_maxk");
