Main menu not selectable on mobile (no mobile theme used)

Hello,

thanks for helping me with this one.

I don’t have a mobile theme installed on https://chillipicks.com and run the latest version of Newspaper (11.4.2, with WP 5.9.2)

The main menu is defined for use in header and mobile menue is also enabled: https://www.loom.com/i/a9fd5efe83b84763a60ce480963906d6

When I access the site on my mobile phone and click on the mobile menu icon (three green lines) the menu does not open up from the left side like it used to but the page is decreased in size and a grey background becomes visible: https://www.loom.com/i/9fd033b611f942a2acaa2f772df2ef41

When I click on the menu icon again the page goes back to the original size.

Can you please advise what I need to do so the menu will work on mobile?

Thank you so much in advance!

Hello Bettina,

many thanks. I will check the guide.
By Rocket Loader do you refer to WP Rocket?
I’m not using Cloudflare.

Thank you

Hello Bettina,

I checked the guide and all the settings are as recommended (for the plugins I use).
On my test site (which is a copy made using All in one WP) the mobile menu is displayed correctly and I also use WP Rocket on it.

It’s really strange.

Thank you for your advice what else could be causing this.

Hello Bettina,

many thanks. It was due to the WP Rocket CDN and their support helped me.

Posting the solution here in case someone else experiences the same issue:

Exclude /wp-content/themes/Newspaper/style.css from RocketCDN

Kind regards
Britta
