Mobile Menu Diagnostic & Fix

The menu items on hamburger icon on nanyanggifts.com no longer responds on mobile. Nothing opens at all, and the problem shows up consistently in Chrome, Safari and Firefox, so it is not browser-specific. I have not touched plugins, themes or any other site settings recently, which means the fault is likely buried in an update, a script conflict or a CSS/JS minification issue that slipped through.

What I need you to do is:

• Locate the exact cause of the menu failing to open (JavaScript error, CSS override, WordPress or theme conflict—whatever it is).
• Apply a clean fix that restores full menu functionality without breaking existing styling or other interactive elements.
• Provide a short explanation of what went wrong and how you corrected it so I can document the change.
• Verify the repair on current versions of Chrome, Safari and Firefox across both iOS and Android screen sizes.

Please work directly on a staging copy if you prefer, or back up the live site before you touch anything; I need zero downtime. Once you confirm the menu opens smoothly and links are tappable, I will sign off immediately.
