--- Comment #8 from Richard Baxter <richardbrucebax...@gmail.com> --- Thanks for your help Physikerwelt, Although Math extension 11 August 2014 was giving a blank screen, version 13 August 2014 was giving a "Failed to parse (<math_empty_tex>):" error. I got it working by compiling texvccheck (or setting $wgMathDisableTexFilter = true;). These are basic installation instructions that I had overlooked (provided by https://www.mediawiki.org/wiki/Extension:Math). Both MW_MATH_MATHML and MW_MATH_LATEXML are now working (with both mediawiki stable 1.23.2 and mediawiki latest 13 August 2014, using a current Math extension build). $wgMathValidModes = array( MW_MATH_PNG, MW_MATH_SOURCE, MW_MATH_LATEXML, MW_MATH_MATHML); $wgDefaultUserOptions['math'] = MW_MATH_LATEXML; As you have mentioned, setting MW_MATH_LATEXML requires reexecution of "php update.php" to prevent a "A database query error has occurred" error (although setting MW_MATH_MATHML does not).
