Hmm, I noticed you have updated Easysocial 4 beta version on your live site.

We do not encourage users to update Easysocial 4 beta version on their live site is because if we add some of the maintenance scripts or add a new table or new column during this beta and RC version, then probably will difficult to upgrade this from the beta version to stable version.

Come back to your question, do you mean that when you at this page https://www.whattodo.com/en/club/marketplaces then you click SV language flag icon then it doesn't redirect to https://www.whattodo.com/sv/klubb/marketplaces ?

If yes, you have to create a menu item for Marketplace for both languages then set have to set the association from the menu setting.
