Hi there!

Thank you for bringing this to our attention, and I sincerely apologize for the inconvenience caused.

To assist you more effectively, may I kindly request temporary administrative access to your site? This will allow me to thoroughly investigate and resolve the issue for you.

Before sharing the credentials, I strongly recommend taking a complete backup of your site to ensure all data remains secure.

Looking forward to your response.

Best regards

If you have that folder: templates\shaper_helix3\sppagebuilder\ajax_contact - delete it.

If not, check addon settings in back-end editor, just open, and check & save (!)
