Hi,
I was able to update the site last week but realized there was an issue with missing css, so I reverted back. I’ve had to add back the missing CSS into the child theme’s stylesheet even though the styles are in the custom plugin directory. Weird huh? Also, the theme was successfully updated in the betasite without issue, so I’m surprised to be getting this error.

Hi Rikard,
Are you checking the following link: https://photo-to-canvas.com? If you are looking that the beta site, the hamburger is showing up. It’s the production site at https://photo-to-canvas.com where the hamburger is not being displayed. I just tried it and it’s not there.
