Thread:Project:Support desk/Problems importing/reply

If you're importing the XML dump through Special:Import, the problem may be that the xml uploaded never gets stored on the server so MediaWiki could open it for reading. Causes may be:
 * The XML is too large, larger than the MAX_UPLOAD_SIZE or MAX_POST_SIZE defined in the php.ini
 * The temporal folder configured in php.ini for uploads is misconfigured, does not exist, the web server has no permissions to write, etc.

If the problem is the first one, try to import a small one (an export of a single page, for example). If that works, you could separate the exported XML into smaller parts, or upload it to the server through ftp and use the maintenance script importDump.php on the server (requires shell access).
