Maximum upload file size: 0KB

Look for a php.ini file in the root of your hosting account and change the upload limit:

upload_max_filesize = 16M
post_max_size = 16M

Or ask your web host to change the upload limit for you.

Same issue here. The php.ini upload_max_filesize already says 64M for me.

Ask your web host to change the upload limit for you.

php.ini? What file’s location?

Was this ever resolved? Is this a bug?

I upgraded my sites to 3.5 yesterday, and get the same error when I try to add media to a post/page. It says, “Maximum upload file size: 0KB.” below the Select Files button. This said 50MB prior to the upgrade as both my php.ini file and my .htaccess files have upload_max_filesize set to 50M. The default server setting itself is set to 20MB. The only thing that has changes is the version of WordPress.

This seems like a pretty big issue to not have been resolved.

1. It’s not a bug.

2. As per the Forum Welcome, please post your own topic. Posting in an existing topic prevents us from being able to track issues by topic. Added to which, your problem – despite any similarity in symptoms – is likely to be completely different.

It’s actually exactly the same the only thing that is not identical to @pskrivanos question is the file name. I assume you don’t want me to create a new topic for every file I’ve tried this with. So I guess as per the Welcome Forum I could add- that I am having 100% without any doubts or variation, the exact same problem.

I suppose I could also add; @songdogtech’s advice didn’t work for me. Which is what I thought I did.
