I have seen this problem intermittently on several MediaWiki versions (1.3.9, 1.4.2, 1.4.4) over the past six months. I'm on a hosting service that gives me no visibility or control of the various Apache settings.
I did spend a half day trying to track this down and found out the PHP session variables that hold the file parameters were not persistent after the verification page. The images were indeed being uploaded to the server, but the session variables were lost. In the midst of my debugging, things suddenly started to work. I reverted back to the original PHP code and life was wonderful. Since my immediate task was to upload a large set of images, I pressed on with that task instead of trying to figure out what was previously not working.
I'm still perplexed. Unless someone at my hosting service is randomly flipping Apache parameters, I don't see why the LimitRequestBody directive is a likely candidate. Something related to session management seems more suspect.

Hi,
I have troubles uploading files. Every time I try to upload a file, my browser sends the file and then i get a "The file you uploaded seems to be empty. This might be due to a typo in the file name. Please check whether you really want to upload this file" message.
My configuration is: MediaWiki: 1.5rc4 PHP: 4.4.0 (apache2handler) MySQL: 4.0.24 Linux media 2.6.12-gentoo-r6 I already tried everything on http://meta.wikimedia.org/wiki/ Uploading_files
file_uploads On upload_max_filesize 2M post_max_size 8M
I looked at that meta page and, although it did have some words about the LimitRequestBody directive in Apache, the way it was worded might lead those not using Apache2 on Redhat to ignore it. It's a general issue for any installation running Apache 1.3 or later. I've reworded the article in hopes of clarifying it. _______________________________________________ MediaWiki-l mailing list MediaWiki-l@Wikimedia.org http://mail.wikipedia.org/mailman/listinfo/mediawiki-l
