Hello Leo,
Thanks for your prompt and helpful assistance.
I tried disabling GeneratePress and activating the Twenty Twenty Two Theme, without success.
I was about to deactivate my plugins, though this is a slow manual one by one process these days because, oddly, the bulk plugin action drop-down menu no longer includes ‘Deactivate’ (or Delete), when I found a code solution which solves the issue for both pages and posts.
In case it helps anyone else here is the code in input into Code Snippets plugin:
function disable_wpcomtoolbar ( $modules ) {
if ( isset( $modules[‘masterbar’] ) ) {
unset( $modules[‘masterbar’] );
}
return $modules;
}
add_filter( ‘jetpack_get_available_modules’, ‘disable_wpcomtoolbar’ );
