Do you have Wp Engine as host?
The problem is the cache of WP Engine. You can contact the support and ask to add a cache exception to the page "Request a Quote" :
My site runs the YITH Woocommerce Request a Quote plugin and we are having some issues with page caching. The Yithemes team has instructed us to ask you to place a cache exception on our request a quote page.
Could you please add the following URL to the exception list?
- [ add the url of the page request a quote ]
In add I need also exclude these cookies:
yith_ywraq_session_ (<-This one is the prefix, a full cookie sample is yith_ywraq_session_8f1b5dab87414a43dc3f816fa5310085)
Are you using a Plugin for Cache the content of your site?
Please, add the page request a quote as exception. This page is dynamic and it can’t have cache.
