Math formulas are not working on ptwikibooks. For an example, see https://pt.wikibooks.org/wiki/Project:Caixa_de_areia?oldid=257996&action=edit&preview=yes&uselang=en where it is displayed the following error: Falhou ao verificar gramática (O executável texvc não foi encontrado. Consulte math/README para instruções da configuração.): K = \frac{1}{2} mv^2 The text comes from [[MediaWiki:math_failure]] and [[MediaWiki:Math_notexvc]], which in English are the following: Failed to parse (Missing texvc executable; please see math/README to configure.) Currently, we are using MediaWiki 1.22wmf6 (b16555d).
Looks like I must've forgotten to rebuild it. Should be fixed now.
The problem is back: https://pt.wikibooks.org/wiki/Project:Caixa_de_areia?oldid=260852&uselang=en It works fine on English Wikipedia: https://en.wikipedia.org/w/index.php?title=Wikipedia:Sandbox&oldid=569396451
Fixed again
