Thank you – I did try clearing the cache but that did not solve the problem. I further did some testing and here is what I found:
I have both W3 Total Cache and Cloudflare activated on the website. I tested 3 scenarios and here is what I found:
– When I disabled both cloudflare and W3 Total Cache – I was able to submit the review
– When I enabled Cloudflare and disabled W3 Total Cache – I was able to submit the review
– When I disabled Cloudflare and enable W3 Total Cache – I was unable to submit the review and saw counter error (when I inspected the element)
Hope this helps.
