I read quite a few posts here with the error:
\nThere was an error trying to send your message. Please try again later.
\nI can tell you I try all recent solutions with no success
\nSo this is my current status:<\/p>\n
WP 4.6.1
\nContact form 7 version 4.5.1
\nFresh install couple times
\nvery simple form, only 4 fields and the Send button. (removed reCaptcha just because it could be a problem)<\/p>\n
Try the solution of replacing wp_mail with mail
\ntry the solution of re-inserting reCaptch keys and also deleting it at all
\ntry the solution of changing pluggable.php
\nnote that is NOT the same error message that was in this faq (http:\/\/contactform7.com\/faq\/after-submitting-the-form-i-get-an-error-message\/) . mean, it’s not SPAM.
\nAny other ideas?<\/p>\n","protected":false},"template":"","class_list":["post-8350897","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/8350897","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/8350897\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=8350897"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
