Thanks for this. The WordPress SEO plugin is immense but those extra columns are just annoying.
As far as I’m aware, you simply change the version number within your style.css e.g. to 1.1 then zip up the folder and upload it again via the Theme Authors section. If successful, you’ll get an on screen message that says, thanks for uploading version 1.1 of ‘Your theme name here’ or similar.
Note to admins, this is a little confusing and certainly not obvious.
I’ve been struggling with this problem all day.
problem occurs on my local server OSX/PHP5/Apache2 and with Dreamhost.
the .htaccess fix (above) doesn’t seem to work on either server all I can get out of the swfupload debug setting is that is is sending back a 500 error. This must be a problem with swfupload/server setting -there seems to be a few complaints in swfupload forums but not solutions.
