I suddenly noticed this morning that my custom fields weren’t showing up in the post edit screen or on my site (guitarnoize.com), I update the site daily (except weekends) and it was fine friday. I may have updated a plugin since then but I can’t remember if I did so I tried disabling all plugins except ACF and ACF repeater, still didn’t show but I got an error message when I tried to save a new test text custom field saying cannot modify header information – headers already sent in /pluggable.php line 876?
When I check the database the images I have been using in a repeater field are still there, the custom field group is still there but it says 0 fields and wont let me save a new custom field or display the existing repeater field and sub fields? I am using the latest version of the plugin, also tried downgrading to 4.1.6 with no luck either. WP 2.5.2
