I have a weird problem.
I created and I am using a Field Group, that is working perfect in my dev installation, but not on the live one.
I have assigned this Field Group to a page template. When trying to customize the different options in the page, the rendering of the admin page stops when a field with type Post Object appears. Everything below it doesn’t get rendered, and even clicking on “Screen Options” doesn’t work.
I have tried creating a test Field Group, and assigning only text fields. No problem. Then I added a Post Object field, and it breaks again.
Any ideas what could be causing this?
Checking PHP error log, I can see PHP Fatal error: Allowed memory size of 67108864 bytes exhausted. Searching around, I have found a post here handling the same, but without answer so far…
