Почему-то при подключении в J!Blank библиотеки lesshat в итоговом css вместо значений некоторых свойств (opacity, box-shadow и др.) получаю такое
filter: /* Sorry, can not do JavaScript evaluation in PHP... :( */; -webkit-opacity: /* Sorry, can not do JavaScript evaluation in PHP... :( */; -moz-opacity: /* Sorry, can not do JavaScript evaluation in PHP... :( */; opacity: /* Sorry, can not do JavaScript evaluation in PHP... :( */;
-webkit-box-shadow: /* Sorry, can not do JavaScript evaluation in PHP... :( */; -moz-box-shadow: /* Sorry, can not do JavaScript evaluation in PHP... :( */; box-shadow: /* Sorry, can not do JavaScript evaluation in PHP... :( */;
