I have the same problem. With The Events Calendar plugin active, I’m not able to link languages between pages or posts, or even assign a language when saving.
However, if I comment this line (line 2937 in “/plugins/the-events-calendar/lib/the-events-calendar.class.php”) it works fine:
remove_action( 'save_post', array( $this, 'addEventMeta' ), 15, 2 );
I don’t know what to do. Using another calendar plugin is not an option in this particular case, and commenting that line doesn’t seem a very good solution.
Same problem here!
After updating to CF7 v3.9 the conditional JS and CSS files don’t load anymore.
In my case, I’m just conditionally loading the CF7 files in the contact page using this method: http://contactform7.com/loading-javascript-and-stylesheet-only-when-it-is-necessary/
Thank you
