I do have the same problem although I did not get an error message. I simply pick up a date in the shown calendar and the field does not grab it or in other wordes the picked date does not appear in the field.
If you have it as a required field it don’teven let you save the post.
This is an annoying bug.
Hello,
I have the same problem. After choosing a date in 2015 i get the following message:
Field “Datum agenda item” not updated: Datum agenda item Please enter a valid date.
I seached on the website op Types Community Support for an answer but could not find it.
Does anyone have a solution?
Thanks in advance.
Ey. You can Downgrade the plugin !! With 1.6.3 works good. I had to do it !
https://downloads.wordpress.org/plugin/types.1.6.3.zip
You will need delete the 1.6.4 plugin directory and insert the 1.6.3 version.
Works fine. Thank you very much, Luiso!
Actually I hate downgrading. I am still not live with my site so I have some more time for waiting. For a live systems it might be a valuable solution though.
Seems that WP 4.1 is about to release these days and OTGS is planning something too. Hope with this new releases will come up a bugfix.
