Media Library and pics in WPMU doesn't work

In addition to checking ownership as Ipstenu suggested, You are saying that /wp-content/blogs.dir/blog#/files/2011/02/image is not working, but that /wp-content/blogs.dir/blog#/files/2011/image is … Does your 02 folder have sufficient (755) permissions?

I know you said you checked permissions, I was just wondering if you checked it on each of the folders in the path along the way to where the image is stored at.

Also try manually FTPing another image to that same folder, then manually browsing to that image and see if it comes up.

[Edit: Oops… I was two minutes late in typing my response

Try the image thing though. I am thinking that there may be a problem with your image itself. Trying to view the image shows me what I might expect if the file format was incorrect, or if it was uploaded in ASCII instead of Binary]

?? other images – the same situation. Try https://nie-opozniaj-piesni.net/sluzew/files/2011/02/butelka.gif and https://nie-opozniaj-piesni.net/sluzew/files/2011/02/butelka.gif

no matter I upload them via ftp, wp or other www-filemanager

Do you have another .htaccess somewhere in any folder starting from your uppermost web root all the way down to the 02 folder? It could be a .htaccess setting. Also, did you check the GID/UID?

No, I don’t

Also, did you check the GID/UID?

Yes, its ok.

But why and what changes with image file saving via two links (via wp link and real)? What causes this?
Isn’t it so that domain/blog/files/image is opening with use of ms-files.php? I don’t know php, could You tell me what does this file do?

The two URLs is to mask the blogs.dir location.

domain.com/files/2011/02/file.jpg points to ms-files.php which translates that as domain.com/wp-content/blogs.dir/1/files/2011/02/file.jpg

It’s supposed to do this. The problem is your ms-files.php isn’t doing the translation right.

the same situation is with other files eg. zip files – downloading via domain/blog/files/2011/02/file are corrupted.

I’m kind of leaning towards ‘Something on your server is seriously messed up, sir.’ I’ve never seen this one before.

You’ve done the whole ‘Turn off all plugins, revert to the default theme’ and it still dies?

That ms-files.php file is either seriously wrong (a reinstall of WP’s core files would have fixed that), or the version of PHP on your server is messed up, or your server doesn’t handle MIME types as well as it should.

the same situation is with all blogs, except main. If You want to, try this two links https://nie-opozniaj-piesni.net/sluzew/files/2011/02/butelka.zip
and
https://nie-opozniaj-piesni.net/wp-content/blogs.dir/5/files/2011/02/butelka.zip

All other links, files, images are ok, only wp links to media directories.

You’ve done the whole ‘Turn off all plugins, revert to the default theme’ and it still dies?

Yes

That ms-files.php file is either seriously wrong (a reinstall of WP’s core files would have fixed that), or the version of PHP on your server is messed up, or your server doesn’t handle MIME types as well as it should.

Reinstall WP didn’t help.
PHP or MIME – maybe yes, something is wrong, but only together with ms-files, cause all other stuff from this server is working fine.

I consider to move files from blogs.dir to uploads or something, inversely to Yours: https://code.ipstenu.org/2010/moving-your-images-for-multisite/
or some htaccess rules for every sub-page…

Do You think it is possible that ms-files.php translate URLs right but files from media library are wrong translated? With or without participation of php on my host…

Have someone of You tried to download one of this files from my links and opened it?

part of ms-files.php. Does it refer to php on server or something inside wp?

$mime = wp_check_filetype( $file );
if( false === $mime[ 'type' ] && function_exists( 'mime_content_type' ) )
	$mime[ 'type' ] = mime_content_type( $file );

if( $mime[ 'type' ] )
	$mimetype = $mime[ 'type' ];
else
	$mimetype = 'image/' . substr( $file, strrpos( $file, '.' ) + 1 );

header( 'Content-type: ' . $mimetype ); // always send this
if ( false === strpos( $_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS' ) )
	header( 'Content-Length: ' . filesize( $file ) );

You can’t do the inverse of my ‘how to move your images’, really, because each separate blog needs it’s own folder (or you will be in a world of hurt). You MIGHT be able to define each to it’s own though.

The ms-files.php is NAMED php so yes, it calls PHP on your server ?? That’s how it works.

Have you checked the file permissions of your other files (such as ms-files.php, etc.) to make sure they are all readable by the appropriate sources? Is it possible that your Web server is not able to read ms-files.php, and is therefore failing to use it?

Also, have you checked your server’s error logs to make sure no clues can be found there?

Didn’t help, smashed everything. Thats why I think its not a htaccess problem but some php function of wp on my server.

@curtiss Grymala
Yes and yes ?? nothing

@ipstenu
Thats how makapu understands php ??

Now I’m almost sure – problem is with some php function in wp, ms-files, function.php or some else. Files downloaded via ms-files are changed rel. to source file on server.
