I am using Mootools and slimbox to open an image slideshow on my site however I want to upgrade Mootools to version 1.2 however just updating the files causes it to break. I think this is because the person who coded the site made some custom changes to the JS files. How can I upgrade to the latest version of Mootools without breaking my current implementation? Here is the page:
I think the problem is that the slimbox.js has changed and it won't run because of the custom code in the new slimbox.js. How can i port these changes to the new version and make it work with Mootools 1.2?
