    We will be glad to help you with your concern and we would like to apologize for any inconvenience the issue has caused you. Based on your screenshot, you encountered the issue while submitting the form from an iPhone? Does the issue only happens in mobile or does the issue always happen every time the form is submitted regardless of what device is used? I have also noticed that the form was submitted via its direct link, is that correct?

    I have inspected your form and I see that it has a PayPal Express set up in it and it is also integrated with Dropbox. Did the error message appear after the payment was processed or after the submit button was clicked?

    May I ask you to try if resaving your Dropbox integration would solve the issue you are having, please?


    We will wait for your response.

    Hi

    The only way I can get it to work is to leave the dropbox integration off


    I have tried it already taking off and adding it back on, But as soon as I add dropbox integration the same error message shows up


    Let me know if you find a fix?

    Apologies for the inconveniences this may have caused. 

    We have been testing this on our end and found the issue you're getting is caused due to a combination of features. 

    - PayPal (Standard and Express)

    - Basic file upload field allowing a single file. 

    - Integration with Dropbox. 

    I will forward this thread to our second level so our developers can further investigate the issue, we will let you know as soon as we receive any updates about it.
