Subject Line is code

Hi there,

Thanks for reaching out to us today. I am happy to help.

It sounds like your email subject line is being encoded. Could you please try the code snippet here to resolve this issue: https://formidableforms.com/knowledgebase/frm_encode_subject/#kb-add-subject-encoding

You can put the code in the Code Snippets plugin, your own plugin, or your theme’s functions.php file. I recommend you put it in the Code Snippets plugin, which has some nice features and will allow you to retain the functionality even if you change themes.

You can read about this in our documentation here:
https://formidableforms.com/knowledgebase/formidable-hooks/#kb-where-to-put-the-code

It would be helpful to test to see if anything on your site is interfering with Formidable and causing the issue.

Could you please go through the following steps?

If the issue doesn’t show up under these circumstances, you can add each item back in, one at a time, and test after adding each one until you find the culprit.

Let me know what you discover.
