 * I’m having a problem trying to submit Constant Contact forms on my sites. They
   load properly on the page but when hitting submit, I get the following error:
   
   Catchable fatal error: Object of class WP_Post could not be converted to string
   in /public_html/wp-includes/formatting.php on line 1031 I have looked at this
   line and it is function wp_check_invalid_utf8( $string, $strip = false ) { $string
   = (string) $string;
 * Please advise?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcatchable-error-when-submitting-form%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Really hard to say what the source of the issue is, truth be told, without what’s
   known as a stack trace and order in which code is called. We don’t invoke the
   function above directly, so it’s something done in between the submission of 
   the form, and the attempted processing.
 * That said, I submitted to the form twice, once without the email confirmation
   checkbox, and once with, and neither time did it give me an error. Not saying
   it’s not an issue, just that thus far I am not managing to recreate.

 * I found that ticking the checkbox ‘Submit via Ajax’ stops the error, but the 
   form still does not perform correctly. In this condition, the form submits and
   the email is sent, but the list is not updated.
 * I have taken this parameter off on this form so you can check the error: [https://opticallabproducts.com/digital-edition-subscription-form](https://opticallabproducts.com/digital-edition-subscription-form)

 * That time it did actually go to that error mentioned above, however that sadly
   still doesn’t give enough information to really know what’s going on and where
   the issue is.
 * Do you know if your hosting is set up to log errors in better detail?
 * Also, if you’re willing to let a support member try to dive in deeper to this
   topic as a whole, please contact [apisupport@constantcontact.com](https://wordpress.org/support/topic/catchable-error-when-submitting-form/apisupport@constantcontact.com?output_format=md)
   and we can take things privately from there. Provide a link to this support thread
   and mention “Michael WordPress Forums” for the subject.

 * Our hosting is set up to log errors but I’m not easily finding anything relevant
   to this issue. I will send an email to api support.
 * Thanks!

 * Found that a plugin was inserting its own content/WP_Post object into the $_POST
   superglobal, and thus our form submission sanitization was fatal erroring due
   to that object.
 * Solution noted and will be in next release.

 * Marking as resolved. This will be addressed in the 1.3.5 release.
