Parent menu is not clickable, Wordpress


Staff member
I have meet an issue with parent menu is not clickable. I have tried all possible as well as my own suggestions into it but did not get any luck.

My site is in wordpress <a href="" rel="nofollow noreferrer">Site</a>

I have also tried the custom link and the main menu work when i set menu as standalone which means no submenu.

Kindly check my website and please provide me solution for the same.
There is a error in console as well.

Uncaught TypeError: Cannot read property 'getElementsByClassName' of null
