Hi @luistinygod
I just wanted to let you know I have fixed a bug in the has_sub_field / have_rows function from another thread:
http://support.advancedcustomfields.com/forums/topic/latest-version-critical-endless-loop-crashes-sites/#post-8025
I’m not sure if it will, but can you please apply this update and reload your issue? Perhaps it will also fix the problem you have.
if not, I’ll look into it shortly.
Thanks
E
