Errors with convert[edit] For those of you who are having problems with convert, something like "Unable to temporary file", it seems to be convert, for some odd reason, trying to create Selinux[edit] On Linux systems with selinux support, such as recent versions of Fedora Core, restrictions enacted by selinux can result in puzzling manifestations. The last attempted database query was: (SQL query hidden) from within function "MathRenderer::_recall".

Something like P ( r ) α r n − 1 exp ⁡ ( − k r 2 / 2 σ 2 ) {\displaystyle P(r)\alpha r^{n-1}\exp(-kr^{2}/2\sigma ^{2})} renders beautifully whereas replacing http://indywebshop.com/failed-to/failed-to-parse-wsdl-document-xml-parser-error-createxmldoc.php Here's what I've tried: (1) compiled and tested texvc system -- it works fine from the command line (2) ensured that dvips, convert, and latex were in the default path -- Another possibility is that you wrote that wiki page before compiling texvc, and haven't rerendered any math since.
