Upgrade two different sites to WP 3. Once upgraded, when trying to add new media, a new warning shows up that file uploads are limited to 2Mb:
Maximum upload file size: 2MB
This is NOT a local server php.ini setting. That setting is 20Mb. (I run the server and have access to php.ini and can verify the settings there.)
Sites running 2.9.2 do NOT have this issue on the same server with the same php.ini file.
OK. What changed? I don't want to hack a bunch of sites to put .htaccess file entries just to fix something that should not have been broken by an upgrade.
