@elliot nothing particularly different about it. Is just my dev server. I haven’t use ACF on this here before though. Oh – apart from that I have to use define(‘CONCATENATE_SCRIPTS’, false); or the admin area refuses to load correctly.
PHPinfo is here http://www.winkreative.stage.glaikit.co.uk/test.php
Was a totally vanilla WP 3.5.2 install. No other plugins.
Have tried earlier versions of ACF with no change.
Looks like the ajaxurl isn’t being populated because the (‘)s for the whole JS file are being escaped and causing a Syntax Error.
