MediaWiki 1.23/Known issues

These are known issues in the current version of 1.23 that we plan to have fixes for in 1.23.1:


 * Short URLs not working on IIS under Windows
 * Thread:Project:Support desk/Short URLs not working after upgrade from 1.19 to 1.23
 * Problems on uploads
 * Temporary files disappear on upload, causing new uploads to fail
 * popen has been disabled for security reasons (and it worked on previous versions)
 * just another report
 * Postgresql database updates fail (confusingly) without $wgDBmwschema being explicitly set to "mediawiki".
