Hi! I am a Happiness Engineer working for Jetpack. A Jetpack user wrote to me today and showed me how, upon submitting a Jetpack form while having your plugin active, he got this error:
Warning: http_build_query(): Parameter 1 expected to be Array or Object.
Incorrect value given in
/home/XXXXXXXXXX/example.com/wp-content/plugins/jetpack/modules/contact-form/grunion-contact-form.php
on line 357
Warning: Cannot modify header information - headers already sent by (output
started at
/home/XXXXXXXXXX/example.com/wp-content/plugins/jetpack/modules/contact-form/grunion-contact-form.php:357)
in /home/XXXXXXXXXX/example.com/wp-includes/pluggable.php on line 1178(I changed the URL, obviously).
He states that the error went away after deactivating CleanTalk. Can you verify this, please? I didn't want to sign up for an account to test it myself. Feel free to open up a Github issue if you feel it's something we can fix on our end:
