Hi, I have a problem with mediawiki 1.15.1 on ubuntu lynx with apache 2. The Latex png rendering stopped working. So far I could find out that texvc works fine and creates the correct png at images/tmp but then the png is not moved to its correct location images/math/x/y/z where xyz are the first hexdigits of the hash key. All folders are owned by www-data and chmodded 777. Any ideas? Philipp
