Added Google Optimize to a website in order to do A/B redirect testing. All working fine except when a user searches for the site using specifically Google: They land on either a/b page for a split second, then appears to change page to Apache testing page. Same home page URL with "?utm_expid=.-gWJoumhTPiomSJCT6Ty1g.1&utm_referrer=https%3A%2F%2Fwww.google.com%2F" on the end of it.

Removing the "&utm_referrer.." from the URL makes it work fine again.

Tried removing referrer variable from google task manager with no luck.

Wordpress website hosted on Plesk.

Any suggestions? Please help!
