Here is what the error looks like in the Chrome Debugger Console: Uncaught SyntaxError: Unexpected identifier tw-sack.min.js:1 If you’r getting a problem with editing forms in GravityForms, or perhaps trying to add fields, you can take a look at the source code and you’ll see what happens – an AJAX request is made, but twsack does not like the response which looks something like: EndAddField({“id”: 1, “label”: “Hidden Field”, “adminLabel”: “”, “type”: “hidden “, “isRequired”: false, “size”: “medium”, “errorMessage”: “”, “inputs”: null}, ” <li id=’field_1′ class=’selectable gfield gform_hidden’ ><div class=’gfield_ admin_icons’><div class=’gfield_admin_header_title’>Hidden : Field ID 1</div><a class=’field_delete_icon’ id=’gfield_delete_1′ title=’click to delete this field ‘ rel=’nofollow’ href=’#’ onclick=’StartDeleteField(this); return false;’>Delete</a><a class=’f ield_duplicate_icon’ id=’gfield_duplicate_1′ title=’click to duplicate this fiel d’ rel=’nofollow’ href=’#’ onclick=’StartDuplicateField(this); return false;’>Duplicate</a><a c lass=’field_edit_icon edit_icon_collapsed’ title=’click to edit this field’>Edit </a></div><label class=’gfield_label’ for=’input_1′>Hidden Field</label><input p laceholder=”Hidden Field” name=’input_1′ id=’input_1′ type=’text’ value=” dis abled=’disabled’/></li>”);m So the problem is actually that the response comes back with a Content-type of json, javascript, or html when it should be returned as text/plain – something like: Content-Type: text/html; charset=UTF-8 To test, I edited the file form_detail.php and changed line 2178 (or rather inserted this line) – for gravity forms 1.7.5 (omit the line numbers): 2178 header(‘Content-type: text/html; charset=utf-8′); 2179 die(“EndAddField($field_json, \”$field_html\”);”); Next I am going to look into changing the .htaccess file for this system to see about editing the default content type which I think is causing the root of the error.
