I have just the same problem.
Could be some way to sincronize with Polylang, please?
Thanks.
Hi,
I have the same problem.
In my local network all dates work.
Now, when I try an old date this error appear at the list of announcements:
Warning: date() expects parameter 2 to be long, string given in ..wp-content\plugins\timeline-express\classes\class.timeline-express.php on line 632
And the date is replace by the current date at the detail.
I copy my local old date from the database to the production database and the problem continue.
(I have already selected all events)
What’s the problem? How could I fix it?
Thanks
