We’re having this issue on a new website we’re developing in French and English.
The filter bar will not translate “Week, Day, Map, Photo”.
Also, on the calendar, the days will be shown in french at first, then when switching months, it will revert back to English.
We checked with codestyling and the translated text is there. Most things that are in the PRO translation will not display, even though the tribe-events-calendar-pro-fr_FR.po and .mo files are in the /wp-content/plugins/events-calendar-pro/lang/ folder.
We use qtranslate to switch website languages.
Any ideas?
