Hello John,
Thanks for your reply.
I put true to WP_DEBUG, but don’t see anything else than previous message. So, to be sure I tried to write line to have the error.log but I’ve nothing in relation with ACF (only 4 errors on wp_cache).
May be I do something wrong with this ?
I’m going crazy with this bug, i’ve tried lots of things, but nothing repair this. It’s pretty sure I got Ajax or PHP error, but I can’t understand why I don’t see anything in my console. :/
