Support » Plugin: WP SIMILE Timeline » Stopped working after upgrade

  • Thanks for the great plugin.

    I’m sad to report after the latest upgrade all the posts disappeared from the timeline.

    I turned on debugging and saw:

    Unfortunately I don’t have time right now to debug your code, but hopefully this gets you started.
