Recently, I've been having trouble with Jquery image animations - but only in Firefox.
I went through and systimatically deactivated all my plugins and narrowed it down to the AddThis plugin. With all of the other plugins loaded and the AddThis one deactivated, the jquery animations work perfectly in all browsers. As soon as I activate the AddThis plugin, the jquery does not work. It sticks on the first "slide" and a person cannot even manually click to see the other slides.
I hadn't updated anything - but do see Google+ was added to the AddThis plugin, so it may be an update within the AddThis plugin that is now conflicting with my site theme. I ended up updating both my WordPress installation and AddThis plugin to the most updated, hoping for a simple resolution, but it errors just the same.
With only the AddThis plugin loaded, this is the warning I get:
A parameter or an operation is not supported by the underlying object" code: "15 http://www.imaginarytree.com/donaldvdmTEST/wp-content/themes/Maxi/js/jquery.img.preload.js Line 88
Here's the page in question (test site):
Any help would be greatly appreciated. Thanks so much!
