yesterday I updated to WordPress 5.5 and right after that I noticed that on mobile and tablet the hamburger menu stopped working. The menu is there, but once I click on the burger, nothing happens. I tested on several different devices. The problem is there.
I tested all plugins, there is no plugin conflict.
I also deleted all the additional css - the problem is not cost by the css.
This is the website affected : https://one-interiordesign.com/
Is there a way you can help me? Thank you so much!
