I setup a mediawiki (1.4.9) site on one of my test servers and had image uploading working perfectly. Then I migrated the entire site to a production server and image uploading stopped working. When I attempt to upload a file, the Upload File page just reloads itself without doing anything.
There are other mediawiki sites running on this same server and the image upload works fine on them so I figure it's not an issue with the PHP configuration.
I've attempted to debug the problem by manually editing includes/SpecialUpload.php and seeing where the code ends up. The code is always ending up going through the last "else" block in this code snippet:
if( $this->mReUpload ) { $this->unsaveUploadedFile(); $this->mainUploadForm(); } else if ( 'submit' == $this->mAction || $this->mUpload ) { $this->processUpload(); } else { $this->mainUploadForm(); }
For whatever reason, which has to be part of the problem, $this->mAction and $this->mUpload variables are NULL/empty every time I attempt to upload a file.
I've modified my file upload variables in LocalSettings.php to be the same as the other wiki on the server that works. Here are the things I've modified there:
$wgUploadPath = "$wgScriptPath/files"; $wgUploadDirectory = "$IP/files";
$wgDisableUploads = false;
## The list of allowed upload file types $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'ogg', 'zip', 'pdf', 'svg', 'tar.gz', 'gz', 'txt', 'doc', 'xls', 'ppt', 'mp3', 'sxc', 'swf' );
$wgFileBlacklist = array( # HTML may contain cookie-stealing JavaScript and web bugs 'html', 'htm',
# PHP scripts may execute arbitrary code on the server 'php', 'phtml', 'php3', 'php4', 'phps',
# Other types that may be interpreted by some servers 'shtml', 'jhtml', 'py', 'cgi',
# May contain harmful executables for Windows victims 'exe', 'scr', 'dll', 'msi', 'vbs', 'bat', 'com', 'pif', 'cmd', 'vxd', 'cpl');
Does anyone have any idea on what I should try next or has anyone else ever seen this problem before?
