Hello, I apologize for posting this as I did post it earlier, but I am at a total loss as to what the problem may be, so I am pleading for help. I upgraded from 1.16 to 1.21 and then 1.21.1. Ever since upgrading from 1.16, I can no longer upload files. It is not a permission or ownership issue, as all directories/sub-directories/files all the way down through and including each parent directory "/var/www/html/wiki/images" have root as owner and group and everything is set for 777. Installed software Product Version MediaWiki<https://www.mediawiki.org/> 1.21.1 PHP<http://www.php.net/> 5.3.8 (apache2handler) MySQL<http://www.mysql.com/> 5.1.60 Entry point URLs Entry point URL Article path<https://www.mediawiki.org/wiki/Manual:$wgArticlePath> /wiki/index.php/$1<http://192.168.56.63/wiki/index.php/$1> Script path<https://www.mediawiki.org/wiki/Manual:$wgScriptPath> /wiki<http://192.168.56.63/wiki> index.php<https://www.mediawiki.org/wiki/Manual:index.php> /wiki/index.php<http://192.168.56.63/wiki/index.php> api.php<https://www.mediawiki.org/wiki/Manual:api.php> /wiki/api.php<http://192.168.56.63/wiki/api.php> load.php<https://www.mediawiki.org/wiki/Manual:load.php> /wiki/load.php<http://192.168.56.63/wiki/load.php> I either get "Could not create directory "mwstore://local-backend/local-public/5/54" or Internal error Jump to: navigation, search Error storing file in '/tmp/php78T3qA': Could not create directory "mwstore://local-backend/local-temp/4/4a".
