In our Moodle we are encountering a problem that we do not know how to solve.
The problem is that the dates are not always translated, an example: a user enters to the moodle and can see the calendar in Spanish but for example the dates of the weeks in the courses he sees in English, maybe he goes back in or recharges the page and see well translated the weeks and the calendar. At another time you can re-enter and you can see everything correctly.
It does not have a defined pattern. Only that only affects the dates.
Our moodle is a 3.5.2 (although the problem we see from 3.5) and the default language of our site is in Spanish.
Can anyone have an idea what is going on?
