Version 3.7.1 of WordPress (multisite)
Version 4.3.0 of ACF
Add a custom field to all pages.
Create a new page, fill it out and save it.
Edit the page.
Click preview, (no problems.)
Without saving the page, click preview a second time.
At this point the page is deleted. I can reproduce this over and over with any post type.
Thoughts?
Hi @tloc
WP 3.7 has introduced quite a few issues with metadata and the preview button, but this is a massive problem!
I’ll test this myself, but I have a feeling that the issue will happen even without ACF (using native custom field value)
If so, this should be reported to WP core.
Thanks
