I’m using NextGen too. Commenting out that line didn’t fix my calendar, though. Since the NextGen update also screwed up the formatting of my thumbnails, I think I’m going to just roll back for now.
I finally managed to get this working alongside the latest NextGen plugin. Here’s what I did:
1) In the plugin’s js folder (wp-content/plugins/ajax-event-calendar/js/), I replaced jquery.timePicker.min.js with the file from https://github.com/thauber/django-schedule/blob/master/project_sample/site_media/js/jquery.timePicker.js
2) On line 30 of the new file, I changed “jQuery” to “$”, ie:
return elm.timePicker || (elm.timePicker = new $._timePicker(elm, settings));
Then I refreshed my browser cache and things started working again.
Even with the newest Version 2.0.17 , when activated, NextGen Gallery bugs Ajax Event Calendar ( impossible to add or modify an event ). So i have to inactivate NextGen … to get Ajax Event Calendar working well.
My site conflicts with latest upgrade of WP 3.6 – it was fine before on IE, now IE is the problem with pop-ups. I tried updating the jquery.simplemodal.1.4.3.min.js to a newer version and renaming the file – but no luck.
Does anyone have a solution. All of the above are about conflicts with NextGen Gallery which I do not have installed.
@gwegster: Wuhu your fix did it for me!! Thanks a lot, hope the author is going to fix this though!
