I have a problem related to the name of the months in the calendar block: when I use Internet Explorer (8) and Opera, the names are in Spanish. However, when I use Firefox (22) and Google Chrome, 2 different things happen. Without login, the names of the months appear in Spanish. When any user login , the months appear in English.
I have checked the browsers language configuration, the settings in all the cases are established in Spanish.
AddLanguage es .es
AddLanguage en .en
LanguagePriority es en
Thanks in advance
