Just 2 minutes and solved.
After I changed the parent page that is EN also to english, page works fine
Noticed this because if I changed the lang of a child page, it dissapeared from the menu. I use show_menu2(
$aMenu = 1,
$aStart = SM2_ROOT+1,
$aMaxLevel = SM2_CURR+1,
$aOptions = SM2_ALL|SM2_CURRTREE,
$aItemOpen = $open,...
