We have define('FORCE_SSL_ADMIN', true); in the wp-config.php so that the front end uses http and the admin uses https. It looks like scripts are being blocked causing the recurrence field not to work.
In the console I see an uncaught “Uncaught TypeError: $(…).bumpdown is not a function(…)”.
Now in the admin when adding an event under Recurrence Rules, I only see a button that says “Add Another Rule” and when clicked only reloads the same page.
Is there any workaround to allow these scripts to load properly even if we use https on the backend and http on the frontend?
If I remove the force ssl rule defined in wp-config and everything is http then everything works correctly as expected.
Thanks so much for the help.
