Attempt to submit corrupted post data.

Hi @scottmckellam ,

We’d be happy to help!

As the Phone field is only available with WPForms Pro, it seems that you are using the paid version of WPForms. If you have an active license subscription with us, could you please submit a support ticket through the WPForms account dashboard when you have a chance? 

From there, our support team will be able to take a closer look at your request. 

However in the meanwhile, I would be happy to clarify your question.

It looks like the issue isn’t directly related to the Smart Phone field itself, but rather a conflict with a code snippet you’ve added, the one for the LeadConnector chat widget.

I’d recommend reaching out to the LeadConnector support team and explaining the conflict it’s causing with WPForms. Feel free to share the details you’ve provided here, that changing the Phone field type to “US” resolved the issue while keeping the widget active. They should be able to offer a proper fix or a suitable workaround from their side.

Hope that helps!

Hi @rajgt1 ,

Thanks for reaching out!

The “Attempt to submit corrupted post data” error can sometimes occur depending on how the WPForms shortcode is added to a page when using a page builder like WPBakery.

If you’re currently using the Raw HTML block to insert the WPForms shortcode, please try switching to the Text element instead — this often resolves the issue. Here’s a helpful guide on embedding WPForms correctly using shortcodes: How to Embed a Form on Your Website

If the problem continues on your end, could you please create a new post on our WPForms Lite support forum? Since this issue relates to a different site, this helps us keep things organized and ensures your question gets the attention it deserves.

Once you’ve created a new post, please share the URL where the form is embedded. We’d be happy to take a closer look for you.

Thanks!
