I didn't catch that. That is definitely poor practice. I'll advise the devleopers of the theme.

Towards the bottom of the linked page there is a list of scripts that are bundled in with WordPress and the handle used to enqueue them so there is no need for theme and plugin developers to include those scripts again as part of their theme/plugin package. </p> https://legacy.forums.gravityhelp.com/topic/jquery-datepicker-error#post-353949 Sun, 30 Jun 2013 11:42:53 +0000 kchaps 353949@https://legacy.forums.gravityhelp.com/ <p>It does appear to be the theme that's causing the issue. The error is misleading because it seem like the datepicker requires jQuery effects, but perhaps it's just a side-effect. </p> <p>Check out this page, maybe some more details.</p> <p><a href="http://kenchapple.com/?page_id=4" rel="nofollow">http://kenchapple.com/?page_id=4</a></p> <p>I have support on this theme as well, but if you have any ideas what the issue is, I'd appreciate it.</p> <p>Thanks,<br /> Ken </p> https://legacy.forums.gravityhelp.com/topic/jquery-datepicker-error#post-353508 Sun, 30 Jun 2013 05:13:37 +0000 Richard Vav 353508@https://legacy.forums.gravityhelp.com/ <p>When a datepicker field is present on a form Gravity Forms doesn't include or require jQuery UI effects so if it is being included on your page it is either coming from your theme or another plugin and the JavaScript error would suggest it is being included in the wrong position. </p> https://legacy.forums.gravityhelp.com/topic/jquery-datepicker-error#post-352676 Sat, 29 Jun 2013 18:07:04 +0000 kchaps 352676@https://legacy.forums.gravityhelp.com/ <p>The site is just running on my dev workstation right now.

I am seeing a Javascript error in Firebug Console when clicking inside my Datepicker text box. The result is that the Datepicker popup doesn't appear.</p> <p>TypeError: $.effects.effect is undefined</p> <p>I did a little bit of googling, and jQuery may have moved the location of effects and not provided backward compatibility. Any suggestions to fix this? </p>
