tiny mice error with 3.3 upgrade and Safari

FORGOT ONE IMPORTANT THING—-

It’s a Network installation, and it works fine (in Safari) on all network sites EXCEPT the main site!

Do you have any plugins in mu-plugins?

MU plugins? Is that still possible after the convergence? I just checked, nothing there.

I can confirm this is a problem, but I get different errors. Using Chrome on OS X:

load-scripts.php:391Uncaught TypeError: Object function (a,b){return new e.fn.init(a,b,h)} has no method 'widget'
load-scripts.php:62Uncaught TypeError: Object [object Object] has no method 'sortable'
5/wp-admin/post.php?post=956&action=edit:551Uncaught TypeError: Cannot call method 'switchto' of undefined

And using the latest Firefox for OS X:

c.widget is not a function
[Break On This Error] (function(c){var a=0,b=9999;c.widget("...lement:this.element},d)}})})(jQuery);
load-s...320fc76 (line 391)
a(".meta-box-sortables").sortable is not a function
[Break On This Error] var postboxes,is_iPad=navigator.userAg...pbshow:false,pbhide:false}}(jQuery));
load-s...320fc76 (line 62)

And this completely breaks JavaScript for the post editor. I have nothing but Akismet turned on and Twenty Eleven is the theme.

Flush your browser cache. I know, I know. But I can’t reproduce this for the life on me.

Flushed and logged out and quit the browser and relaunched, still the same problem. Maybe I’ll try a restart. Absurd, but I have to try.

I can’t reproduce it for the life of me, and I use a Mac with Safari all the time.

Did you try manually reinstalling the core WP files?

I banged my head against the wall for a while and finally decided to upgrade my OS to 10.6 – and the issue is resolved.
