Navigation block overlay not working on mobile

Hi @kdenby – I can see that issue happening on your site, but can’t seem to recreate it on a fresh installation with Twenty Twenty-Three active.

This may be a plugin conflict – could you please attempt to disable all plugins to see if it makes a difference?. If the problem goes away, enable them one by one to identify the source of your troubles.

If you can install plugins, install and activate “Health Check”: https://www.ads-software.com/plugins/health-check/
It will add some additional features under the menu item under Tools > Site Health.
On its troubleshooting tab, you can Enable Troubleshooting Mode. This will disable all plugins, switch to a standard WordPress theme (if available), allow you to turn your plugins on and off and switch between themes, <strong>without affecting normal visitors to your site</strong>. This allows you to test for various compatibility issues.

There’s a more detailed description about how to use the Health Check plugin and its Troubleshooting Mode at https://make.www.ads-software.com/support/handbook/appendix/troubleshooting-using-the-health-check/

Thank you @jordesign – very useful feedback. Primarily that the problem was confined to that site only so again thanks for trying to replicate it. Once I started disabling plugins the culprit was revealed as WP Fastest Cache … but the real culprit was me who had turned up the caching functions but not ticked the box for :

Mobile – Don’t show the cached version for desktop to mobile devices

Ticking that box has fixed it.

Cheers
