BockUI jQuery …

Same error for me.

and then when I try to upgrade to the standard vision it crashes my whole site.

Had the same jquery version issue.

Uninstalling and reinstalling the plugin resolved the issue for me.

I am participating in the two strings below… the issue seems to be related to the core JQuery update and this plugin’s code

Until the update drops, the fix is here:

I just sat down to try knappen’s approach (which makes perfect sense to me by the way) and lo & behold on a fresh install of WP3.6 & all-in-one-calendar ver#1.10 there was NO PROMPT to update the plugin after install as with prior attempts … and hence no issues.
Makes me wonder if time.ly was pushing an incorrect update and has stopped doing so…
Funny thing, if you try to download the plugin directly from https://www.ads-software.com/plugins/all-in-one-event-calendar/ you get a 404 page, but the download directly from https://time.ly/ works just fine.
I’m feeling more comfortable with the idea of using this plugin. but sure wish that the plugin author would jump into one of these strings with a comment!
