If you see “An undocumented error has occurred. Please reload the page and try again,” or a scanner UI never finishes, another plugin’s JavaScript may be conflicting.
- Open the Security Ninja screen where the problem happens.
- Open your browser developer tools.
- Go to the Console tab.
- Reload the page and note any red errors (file name and plugin path are often in the stack).
WordPress documents browser debugging here: Using your browser to diagnose JavaScript errors.
If the console points to another plugin, deactivate that plugin and retest. You can also deactivate plugins one by one. See Plugin conflicts. If you need help, send the console error text to support.
