Ok found a work around,
Remove the instance hidden field from the forms and it should work.
Also don’t send the instance as in the pastebin above.
However this work-around will break widget, in my case it’s fine cause I don’t use them anyway.
Would be great if there could be an option to post_to_template = true/false (default)
False alarm! Cloudflare’s HTML Minify strips wp-super-cache comments! Disabling it on CloudFlare and re-testing gives timestamp ok!
I’m curious to know as well. Hosting WP on Windows server and mail() is disable as well :/
Did you come up with a workround in the end?
