                            <p>This usually happens if Tampermonkey lacks permission to access and modify protected HttpOnly cookies. Without this permission, the script cannot properly wipe your session cookies.</p>

                            <p>First, check the "Use in Payload" box on your desired reference. A green button (e.g., <code>➕ &lt;IMAGE_0&gt;</code>) will become active next to the "Use in Payload" toggle. You can click this green button to instantly insert the correct tag into your prompt.</p>
                            <p>Do note that numbering can change if more references are enabled or disabled. To verify which image a tag belongs to, look at the small preview thumbnails just above the prompt text box. Hovering your mouse over the <code>&lt;IMAGE_X&gt;</code> tag inside the prompt will highlight the matching thumbnail!</p>

                            <p>This is an intentional safeguard. If a prompt triggers a filter or is otherwise blocked, the script assumes you don't want to keep doing API calls on a prompt that will continually fail.</p>
                            <p>You can disable it by unchecking the "Break loops if one iteration fails entirely" option in the settings.</p>
