Problem: When you click on a category in the dropdown menu, it redirects to a secondary language, such as from English to French. Solution: We recommend first clearing both your browser cache and server cache to ensure no old data is causing the issue. Additionally, if you are using any redirection or code snippet plugins, we suggest disabling them temporarily to test if they are affecting the behavior of the dropdown menu.
If the issue persists and the solution provided here becomes irrelevant due to updates or it does not apply to your case, please visit our support forum to open a new ticket.
