Error: Attempt to submit corrupted post data

Forms have been working with no problems for years. Then a couple of weeks ago, the forms stopped sending. Error message: “Attempt to submit corrupted post data.” I was easily able to resolve the problem by creating new reCAPTCHA keys. Yesterday (a user brought it to my attention) that error message came up again. After 3 key resets, error still happened. Tried:

1. deleting reCAPTCHA from Google and creating a whole new setup,

2. removing then setting up reCAPTCHA again in the forms,

3. deactivating/reactivating wpform plugin, and

4. created all new forms.

I still cannot resolve this corrupted post data problem. Is there a definitive solution? All I can do at this point is take reCAPTCHA off my forms.

Hi Ralden,

Thank you! I’ve been trying everything I can think of, and clearing cache after every change, and still get the error message. https://growingroots.com/long-beach-thousand-oaks-interior-plants/

Hi @des2019,

Thanks for sharing the form URL.

I could reproduce the “Attempt to submit corrupted post data” error, but there is an error on dev tools > Console (screenshot):
```
Uncaught ReferenceError: wpforms_settings is not defined
    at Object.loadValidation (wpforms.min.js?ver=1.9.5.2:5:916)
    at HTMLDocument.ready (wpforms.min.js?ver=1.9.5.2:1:280)
    at e (jquery.min.js?ver=3.7.1:2:27028)
    at t (jquery.min.js?ver=3.7.1:2:27330)
```
When you get the chance, could you please try using the steps in WPBeginner’s detailed guide on troubleshooting WordPress to see if it helps resolve the issue?

I hope this helps! If you have any questions or need further assistance, please feel welcome to let me know.
