Troubleshooting

Script does not run

Check in this order:

1. Red "User scripts are disabled" banner in the popup or dashboard. If shown, enable Allow user scripts for CodeTweak in chrome://extensions.
2. @match pattern.
3. Script is enabled.
4. @run-at timing.
5. Console errors.

Quick test:

console.log('script loaded', location.href);

GM API is undefined

Cause: missing @grant.

Fix:

// ==UserScript==
// @grant GM_getValue
// @grant GM_setValue
// ==/UserScript==

Cross-origin request fails

Cause: external requests disabled in extension settings.

Fix:

• Enable the external resources/request setting in dashboard.
• Retry request.
