Error message

Neither $.cookie or store is defined. A storage solution is required for storing state

What it means

Emitted by Nag's storage remove() (nag.js:252-253) when neither the configured storage backend nor $.cookie is available. Distinct from noCookieStorage only in that it fires on the remove path (e.g. clearing a dismissed nag) rather than set/get. It is a console.error (nag.js:310), not thrown.

Solutions

1. Provide a working storage adapter (jQuery cookie plugin or available localStorage).
2. Feature-detect storage availability before initializing nag.
3. Set storageMethod to a backend supported in the current environment.

Example fix

// before
$('.nag').nag('clear'); // no storage adapter -> noStorage error
// after: ensure an adapter exists first
if (window.localStorage || $.cookie) {
  $('.nag').nag('clear');
}

// Guard dismiss/clear when no storage backend is available.
function storageAvailable(){
  try { return !!window.localStorage || $.cookie !== undefined; }
  catch(e){ return $.cookie !== undefined; }
}
$('#nag .close').on('click', function(){
  if (storageAvailable()) $('.nag').nag('clear');
  else $('.nag').nag('hide');
});

When it happens

Trigger: Calling nag dismiss/clear when no storage adapter is present — same conditions as error 73 but on the remove operation (nag.js:249-254).

Common situations: Missing jQuery cookie plugin combined with unavailable localStorage, incognito/sandboxed runtimes, dismissing a nag that was never persistently stored.
