Collect error when trying to submit: "Failed to upload. Please make sure the form is configured to accept submissions on the server"

Dear community,

We are having the same Error message for our forms.
Is there a solution, please?

Thank you.

Hi and bienvenue, @Fanilo_Andrianisaina!

What server are you using? Have you verified that the form is accepting submissions? What is the formid of the form?

Hi LN,

We are using

Yes, the form is accepting submission. There are other submissions that are accepted, but some aren't (most of them with > 100 repeat answers).

Here is a scrennshot of the Settings.

You should reach out to Ona about this. Given that you're seeing an issue with particularly large submissions, it's likely to be an issue on their end.
