502 errors with multi-step form using form persist
Hi Ray. Im not sure if you can recall my multistep form using form persist to hold data from each step. Everything is working fine locally. I have today uploaded the new site to the remote server and there is some issues. So step one page loads fine. But as I advance to other steps I get 502 errors. I then clear cache and the page loads again. But If I click to previous step then click the next button again it causes 502 error again.
I've attached a screen recording showing you this.
Thanks in advance!
