Hi, I have a very strange issue on my worpdress website. After the update of WordPress and of ACF Pro, some fields are not saving anymore and the flexible field is not visible anymore in front end.
I had no issues like this before and didnt touch the fields so I guess its a problem from the database. In order to fix an issue with the meta data of picture I also used this plugin : https://wordpress.org/plugins/fix-my-posts/ that update all post_name. I think it was a big mistake and it seems that it must have messed with ACF and some fields cant be save. The issue appears on various fields : WYWSG fields, Image fields (it even show an id instead of the url whereas it was showing the picture before),
I have no errors in WPDEBUG and I don’t know where to begin to fix this
Thanks for your help.
