Hello everyone,
I am running a wiki for a research project with access restricted to the participants. So far, it works quite well, but there is a problem with a file upload.
When trying to upload a certain .ppt file, the data seems to be sent to the wiki (according to the browser's progress bar), but when it should be finished, all I (as well as the contributor whose file it actually is) get is a blank upload form. However, this only occurs when I try this from home. When I'm at work, i.e. in the same local network as the server the wiki is on, I get to the file's description page, and the file is shown correctly in the file list (which it is not in the former case).
Even more confusingly, uploading different .ppt files (smaller as well as larger ones) seems to work fine from everywhere, as is the case with other file types (e.g. pdf). But when I convert the ppt file mentioned above to pdf (using StarOffice), the result will not be uploaded correctly either.
I am aware of the advice given at http://meta.wikimedia.org/wiki/Uploading_files#I_get_a_Blank_Screen_.28IE.29..., but it was not helpful in my case.
MediaWiki version is 1.6.7 (I set it up a while ago, and it was hardly ever used since; futhermore, the server, on which I do not have admin privileges, has only PHP 4.3.4). The relevant lines in my LocalSettings.php are $wgEnableUploads = true; $wgUploadPath = "$wgScriptPath/img_auth.php"; #"prevent not logged-in users from accessing files $wgUploadDirectory = "$IP/files"; $wgCheckFileExtensions = false; $wgStrictFileExtensions = false; $wgUploadSizeWarning = 8 * 1024 * 1024; $wgVerifyMimeType = false;
In the php.ini, memory_limit is 64M. I also tried $wgMimeDetectorCommand= "file -bi" as described on the page linked above, but on solaris (afair), the file command seems to work slightly different, and since $wgVerifyMimeType is false anyway, this should not have any effect, should it?
Thanks in advance, Arne
