Thread:Project:Support desk/Upgrading 1.19 to 1.21.1

After upgrading i've some troubles with displayng links to uploaded files.

In 1.19 it was alltight. After upgrade when i want to see full link to file, i see somethin like that: file:///somefile.pdf

I've checked permissions, path, permissions of tmp directory and needed modules. PHP and MediaWiki debug doesn't show me anything.

Tried some variants from this: https://www.mediawiki.org/w/index.php?title=Special:Search&search=uploaded+files+after+upgrade+ondiscussionpage%3AProject%3ASupport+desk&fulltext=1&ns90=1 Nothing helped.

Old version was on FreeBSD and PHP 5.4.4. New version is on Ubuntu 12.04 and PHP 5.3.10.

Can you give any suggestions?

Update: If in text of page i write something like "", all work fine as i need.
