I think that I see the problem, but no idea which component or plugin causes it. When we submit the comment the response is:
<html><head><meta charset="UTF-8"><script type='text/javascript'>(function() { var as = document.createElement('script'); as.type = 'text/javascript'; as.async = true; as.src = '/fireshield.js?t=6n4caj0m7bj8gr6hk0154ik31j6b5g243m153l4m29kindakj8ns5sb7sc6u98ien2768m319lb99kq3jca1hav83kpp1hl5gmgh4qbvgm918bc1n9rrfqti3kq2148vueql72o7sdg9t9n7os8e3u2hk84ge7l81paql8ckk30vip3iu3hbrtrfrtdd2rim036jqtp0719asif2vbabh0ulalboq51l8dcjg8oe869ccc37hppeai1jlktsfv3b'; var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(as, s); })();</script></head><body></body><script>setTimeout(function() { location.reload(); }, 500); </script></body></html>
instead of our json, your site returns some javascript - fireshield? I have the suspition that this is something from your hosting, cause I saw something similar when I tried to access your backend.
