mp3 upload fail – Invalid argument supplied for foreach()

Ditto. Big problem across multiple sites. Help.

Are you running Magic Fields? https://groups.google.com/group/magic-fields/browse_thread/thread/e4f19adbdf3afa5b?pli=1

Im having this same issue also, except:

1. As an admin I can insert uploaded files into the post – BUT as a non-admin, one cannot.
2. File is always successfully uploaded – even though it constantly shows the error message mentioned above.
3. Doesnt happen with images.
4. Im using More Fields, Adminize, Capability Manager and Post Control plugins.

Can someone please help – my websites cant function until this gets resolved?

Thank you.

Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, try switching to the Default theme (WordPress 1.5 – 2.9.2) or the Twenty Ten theme (WordPress 3.0 and higher) to rule-out a theme-specific issue (theme functions can affect the admin panel).

Thanks James- I found a bug with smooth slider after going all the wya back to the theme change –

I appreciate yourhelp – thank you so much!

You’re welcome!

Just wanted to add my thanks, I had exactly the same problem and like graphite_wp I found the problem was down to Smooth Slider 2.3.2. Rolled back to 2.2 and the problem went away.
