WordPress MU

Hello,

Upload File Types (in mydomain/wp-admin/wpmu-options.php): jpg jpeg png gif mp3 mov avi wmv midi mid pdf doc xls sxw sxc ods odt ppt sxi odp

But I can't upload sxw/sxc/ods/odt/sxi/odp files (Error message: "File type does not meet security guidelines. Try another. Back to Image Uploading").

What's the problem?

Thanks

Did you edit this information directly in the wpmu-options.php? If so, that will only modify wp-mu settings for *future* blogs.

You still need to use the WPMU Admin and make the change there for any blogs already set up:

Site Admin | Options | Upload File Types

Same post different answer. This is not hard to fix at all.

This didn't work for me. I still can't upload file types that are specified in Site Admin | Options | Upload File Types

"If so, that will only modify wp-mu settings for *future* blogs."

How is that possible if the database does not contain filetypes per blog?
