You do not have sufficient permissions to access this page

Does this happen with all users? Or only some?

I suspect that the switch does work and then you are being redirected by another plugin to a page that you don’t have access to.

Can you try deactivating your other plugins one by one to see if one of them is causing the issue?

Yes, this happens with all users, and I don’t see any that can redirect the user change, but I could be wrong. I will pass you the list. Thanks

Hi, I have the same pb with my sites. To have access to admin page, I put this code in functions.php

But I cannot let the code, too dangerous. How to have a real fix

function codelight_all_permissions( $allcaps, $cap, $args ) {
$allcaps[$cap[0]] = true;
return $allcaps;
}
add_filter( ‘user_has_cap’, ‘codelight_all_permissions’, 0, 3 );

I my case was a conflict with “wp responsive gallery” plugin
