# Redirect Issue – Query Param Underscore

 * [5 years ago](https://wordpress.org/support/topic/redirect-issue-query-param-underscore/)
 * We uncovered an issue when using the “Ignore & pass parameters to the target”
   option for Query Parameters tied to UTM parameters.
 * If we have a url like this it works fine:
 * [https://testurl.com/test/?utmsource=test](https://testurl.com/test/?utmsource=test)
 * But if the param variable has an underscore, it fails:
 * [https://testurl.com/test/?utm_source=test](https://testurl.com/test/?utm_source=test)

 * Fails how? As a source? As a target?

 * Hi John,
 * It’s failing as a source. If there is underscore in query string parameters in
   source then query string parameters are not passed to target.
 * Source: [https://example.com/page1/?utm_source=test&utm_method=sample](https://example.com/page1/?utm_source=test&utm_method=sample)
 * Ignore and pass all parameters
 * Target: [https://targeturl.com/page2/](https://targeturl.com/page2/)
 * Query string parameters are not passed to target in this case with redirection
   plugin.

 * Are you on WP Engine by any chance?

 * Yes we are on WP engine. Is there any limitation here if so what are our options
   here ?

 * You need to talk to WP Engine. They remove UTM parameters.
