If you keep on receiving a blank page, this usually means that a PHP
error occurred. Check your apache error log.
OK, this is interesting. I found this in the apache log:
[Thu Feb 10 22:58:47 2011] [error] [client ::1] PHP Warning: Missing argument 3 for UploadFromUrl::initialize(), called in /var/www/mediawiki2/includes/api/ApiUpload.php on line 93 and defined in /var/www/mediawiki2/includes/upload/UploadFromUrl.php on line 35 [Thu Feb 10 22:58:47 2011] [error] [client ::1] PHP Fatal error: Call to undefined function curl_init() in /var/www/mediawiki2/includes/upload/UploadFromUrl.php on line 102
The first message show me a bug in the code, because the file UploadFromUrl.php defines the function: *public function initialize( $name, $url, $na, $nb = false )* but never use the two last parameter inside the code: global $wgTmpDirectory; $localFile = tempnam( $wgTmpDirectory, 'WEBUPLOAD' ); $this->initializePathInfo( $name, $localFile, 0, true ); $this->mUrl = trim( $url );
Hopefully, it's very easy to fix :-)
The second message is about curl, as I suspected, it's not working. Could I add to a precompiled installation of php?
