I have been using the MLS plugin without any problems. I recently updated my WordPress install to 3.4 and also updated the MLS to version 0.9.6.
Now I can no longer set an association between posts or pages in the Edit -> Post or Edit -> Page screen.
If I am creating a new page in English, I select the corresponding page in French and click "update" but the setting is not saved. All of the associations that I created before DO still work. I just cannot create new ones.
Any help would be much appreciated.
