I have the following problem:
In article I have created a selectbox “authors”, eg:
aa: Firstname Lastname
bb: Firstname lastname
cc: Firstname lastname
After saving the post, the selected author is displayed correctly in the selectbox (backend).
When I click on publish, the value is not saved and the displayed author is no longer activated in the selectbox. (Also in frontend)
Now it gets crazy: When I click Update (Article) again, the author will be saved again.
Have you ever had this problem?
WP 4.9.8
ACF 5.7.9
Many Thanks
André
After cleaning the DB, it works.
