# \[Troubleshooting] How to avoid being assigned to a test – the optout method

The opt-out method enables you to know if a running AB Tasty campaign is causing an issue on your website.

## When should you use it? <a href="#h_01ggf3s955wc42qdrgh9e5wg39" id="h_01ggf3s955wc42qdrgh9e5wg39"></a>

You should use the opt-out method if you encounter a problem on your website (infinite loop, blank page, internal errors, etc.) and you need to understand quickly to correct it. Using the opt-out method allows you to deactivate AB Tasty momentarily only on your browser to analyze whether a campaign is causing the issue.<br>

## How to use it <a href="#h_01ggf3shcwhxaczxtnra11mqjq" id="h_01ggf3shcwhxaczxtnra11mqjq"></a>

To use this method, add the **#abtastyoptout=1** code to the end of the URL of the page you have identified as having an issue. For example: <http://www.abtasty.com/#abtastyoptout=1>

For the parameter to be taken into account, don’t forget to refresh the page once you have added this to the URL.

## How does it work? <a href="#h_01ggf3tmft1e26vwwnhv9j46c6" id="h_01ggf3tmft1e26vwwnhv9j46c6"></a>

This parameter creates a cookie in your browser to store the opt-out information.

This cookie will block the AB Tasty tag and make all campaigns inactive. This can be verified by checking the **ABTasty.results** value in the console.<br>

**Undefined** means that the AB Tasty tag is deactivated, and you are not assigned to any campaigns at the moment.

\
To unblock the tag, you should delete your cookies (or at least the **ABTastyOptout** cookie). Once deleted, you’ll be able to see your campaigns again.
