Need help fixing template after update

A site I manage is still using an old Wordpress template from 2010 that was removed from Themeforest (and everywhere else on the internet), and the guy who made the template shut down his website and doesn’t answer any emails. Anyway, I’m not too savvy when it comes to the technical aspects and coding behind the template, so I was hoping someone could help me out (assuming it’s an easy fix).

When I upgraded to the latest version of Wordpress, the main menu’s highlighting effect stopping working correctly; previously, when a different menu item was hovered over, the dark yellow “bubble” would slide over and highlight it. When you took the pointer off the menu item without clicking, it would slide back. It’s not an integral component to the site, but it was a neat effect and I’d like it back, if possible. Though I do know the basics of how to go in and edit the theme, I have no detailed knowledge of how to isolate the problem.

Here’s a link to the website: http://birminghamsealcoat.com/

Thank you very much for your help.

Apparently it’s called a “lavalamp menu”.

I would imagine (and i stand to be corrected here) that given Lavalamp menus operate using Javascript that your problem is some form of conflict between older JS files and the new Wordpress installation.

Without seeing the files I can’t really help but if you really want to get the effect back (and are prepared to pay for it – I imagine not much because it should be pretty simple) email me at charlie4282@hotmail.com and I can put you in touch with a freelancer who will def be able to help you.

You seem to be missing a javascript file

My guess is that that is not helping the problem
