The method you called is not defined.

Error message

The method you called is not defined.

What it means

Generic Semantic UI method-not-found error thrown by the visibility behavior's invoke dispatcher (visibility.js:1164). Calling $('.selector').visibility('nonExistent') walks the module internals and, finding no matching function, logs this error.

Solutions

1. Verify the method name against the Semantic UI Visibility docs for the installed version.
2. Use the canonical methods: refresh, destroy, disable, enable, etc.
3. Reinstall/rebuild Semantic UI if a known method is unexpectedly missing.

Example fix

// before
$('.ad').visibility('refesh');
// after
$('.ad').visibility('refresh');

var VIS_METHODS = ['refresh','destroy','disable','enable'];
function safeVisCall($el, method) {
  if (VIS_METHODS.indexOf(method) === -1) { console.warn('Unknown visibility method:', method); return; }
  return $el.visibility(method);
}

function isKnownVisibilityMethod(name) {
  return ['refresh','destroy','disable','enable'].indexOf(name) !== -1;
}

When it happens

Trigger: Invoking a misspelled or unavailable visibility method, e.g. $('.el').visibility('refesh'), or calling a method from a newer version on an older build.

Common situations: Typos; copy-pasting code from docs of a different Semantic UI version; calling private methods without the correct prefix; misusing visibility methods that belong to sticky instead.
