There are 3 potential causes on that thread, unfortunately, none of them help us:
- Toolset Version 3.4.14 - we’re already using it
- Cacheing - no cache plugin installed, WP Engine Object Cache is off, WP Engine cacheing excludes admin (Server and Browser Cache - Support Center)
- Use the Editor Option instead of Blocks - we’re already using Classic.
If I understand correctly here, your custom field is a WYSIWYG field correct ? If such is the case then it is related to our erratas page and as such a likely fix will come from the wordpress core itself.
Given such is there case there isn't much we can do in terms of resolving this.
However what I can do is to check on your site to confirm if it is the same issue. Also would it be ok if I took a copy of the site to provide to our Team as well.
I've enabled the private fields for your next response. Please also send me a link to the post that has the issue.
I've tested using the text tab on the WYSIWYG editor and it works when you've provided the content. However we don't have a solution at the moment for this one.
It should be noted that it works in one post that I tested but i'm unsure if it work work on all the posts.
