Thread:Project:Support desk/Can't upload non-image files - $wgFileExtensions set

Hi! I'm using MediaWiki 1.17.0 with PHP 5.2.17 and having problems getting the upload file feature to work with files other than images. I read Manual:Configuring file uploads. I enabled some extensions, disabled Mime check (worth a try) and emptied the blacklist (for testing):


 * $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'ppt', 'pdf', 'psd', 'mp3', 'xls', 'xlsx', 'swf', 'doc','docx', 'odt', 'odc', 'odp', 'odg', 'mpp');


 * $wgVerifyMimeType = false;


 * $wgFileBlacklist = array;

The upload screen indeed claims I could upload all these file types, but when I try to upload an xlsx or odt, it's not working (message about allowed file types turns red as if I was uploading a forbidden file). File size is not an issue since the images that work are larger than the documents. Did I forget to configure something?
