This thread is resolved. Here is a description of the problem and solution.
Problem: I use The Events Calendar plugin. When I switch the month in the Calendar, the name of the months is not correctly translated. Solution: When you switch months, the calendar is refreshed using AJAX. This is the cause of the language switch.
To solve this, follow these steps: - Go to WPML -> Languages - Scroll down to the "Language filtering for AJAX operations" section. - Enable the "Store a language cookie to support language filtering for AJAX" option - Save
This is the technical support forum for WPML - the multilingual WordPress plugin.
