Maths don't work anymore after updating Math extension. PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)
Yes. The configuration has changed. You can either disable the additional security check via setting $wgMathDisableTexFilter = true; in LocalSettings.php or run make in the texvccheck subdirectory.
Sorry I didn't know configuration has changed.
My fault. Should have been documented.
