After upgrading to v1.5.2, I noticed my form stopped redirecting to a referring page. After digging deeper, I noticed my hidden field that I had configured to be auto populated with the HTTP REFERER variable (i.e using the {referer} GF variable) wasn't being populated any more. So, I downgraded the GF plugin to v1.4.5, which is the version I was on before I upgraded, and sure enough the hidden field was correctly populated again. Do you have a fix for this? Thanks.
