Form Editor related javascript problems are typically caused by these 2 things:</p> <p>1) A PHP memory issue related to a lack of available PHP memory which causes problems with the form editor AJAX from being able to execute. The solution to this is to increase your available PHP memory. I recommend a minimum of 64 MB but preferably 128 MB or 256 MB. Here is information on how to do so:</p> <p><a href="http://www.nerdgrind.com/increase-wordpress-and-php-memory-limit/" rel="nofollow">http://www.nerdgrind.com/increase-wordpress-and-php-memory-limit/</a></p> <p>2) A plugin or theme conflict caused by another plugin or your theme outputting code on the Gravity Forms Form Editor page that should not be there. To see if this is the issue you would have to test for plugin and theme conflicts by following these instructions:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Testing_for_a_Theme/Plugin_Conflict" rel="nofollow">http://www.gravityhelp.com/documentation/page/Testing_for_a_Theme/Plugin_Conflict</a></p> <p>I recommend testing in that order. A PHP memory issue can masquerade as a plugin or theme conflict because when you deactivate plugins and themes it frees up PHP memory. Then when you activate them again, it uses that memory again. So it's best to first look at the memory and increase it before testing for conflicts. </p> https://legacy.forums.gravityhelp.com/topic/jquery-error-when-editing-field-values#post-42944 Fri, 02 Dec 2011 18:15:38 +0000 Stylmark 42944@https://legacy.forums.gravityhelp.com/ <p>I'm also getting this error on 3.2 after a new install except it affects all form field types. As soon as the form is saved the error begins to occur and existing fields are unable to be edited.
