[Plugin: Auto ThickBox Plus] Thickbox not loading

Hi pandameow,

Thank you for using Auto ThickBox Plus.

Did you see the plugin FAQ page?

Auto ThickBox Plus does not work
Most likely, some sort of JavaScript error has occurred in your blog. Please make sure that you can see any messages (errors/warnings) in browser console.

Then you use Head JS and W3 Total Cache.

If JavaScript errors have occurred, ThickBox may not work even when loaded properly. If you use cache plugins such as W3 Total Cache and Head Cleaner, try to deactivate them first.

If you use Head JS, select [General – ThickBox Resources – Footer] option.

I found the following JavaScript errors in your site.

Uncaught TypeError: Object [object Object] has no method ‘placeholder’ (59669f27.44ae03.js:1004)
Uncaught ReferenceError: tb_options is not defined (snapshot-reflexiones-reflections-opening-at-cafe-con-leche:252)
Uncaught TypeError: object is not a function (59669f27.44ae03.js:12)
Uncaught TypeError: Cannot read property ‘client’ of undefined (/wp-content/plugins/wpng-calendar/js/functions.js?ver=0.85:49)

And you use wpng-calendar but it loads jQuery and ThickBox scripts without using WordPress function. So there are jQuery and ThickBox conflicts in your site. You need to modify wpng-calendar if you want to use it.
