The method you called is not defined.

Error message

The method you called is not defined.

What it means

This error is logged by the Semantic UI site module when a method name passed to $.site('some.method') does not match any property in the module object. The module's invoke function (site.js:346-404) traverses the module object by splitting the query string on dots/periods; if no matching key is found at any depth, it logs this error. The error is informational — it tells the developer they are calling a non-existent method.

Solutions

1. Check the Semantic UI site module documentation for the correct method name.
2. Inspect the module object: console.log the methods available via $.site.settings to see valid method names.
3. Remove the invocation or correct the method name spelling.

Example fix

// before
$.site('chnage.setting', 'debug', true, ['accordion']); // typo

// after
$.site('change.setting', 'debug', true, ['accordion']);

// Validate method name before invoking
var validMethods = ['change.setting', 'setting', 'enable.debug', 'disable.debug', 'enable.verbose', 'disable.verbose', 'enable.console', 'disable.console'];
if (validMethods.indexOf(methodName) !== -1) {
  $.site(methodName);
} else {
  console.warn('Unknown site method:', methodName);
}

// Type guard for site module methods
function isValidSiteMethod(name) {
  var valid = ['change.setting','setting','enable.debug','disable.debug','enable.verbose','disable.verbose','enable.console','disable.console','destroy'];
  return typeof name === 'string' && valid.indexOf(name) !== -1;
}

When it happens

Trigger: Calling $.site('nonexistent'), $.site('change.setting', 'key', 'val', ['wrongModule']) where 'change.setting' is mistyped, or passing a method name that was renamed or removed in the current version. Also happens when a module name in the modules array does not exist.

Common situations: Typographical errors in method names, version mismatches after upgrading Semantic UI (method renamed), or calling a method that belongs to a different module than 'site'. Also common when copy-pasting code examples from a different version's documentation.
