Hi, I am trying to create a form, i currently have approx 30 questions but still need to add more but won't let me save the form if I add anymore, is there a limit and if there is can I increase the limit? Thanks Katie
Thanks, that is making it easier, however I still reach a certain spot and it won't let me save, it says - Failed to Save Form - and it just won't let me add anymore once i reach this point. Is there anyway I can check what the problem is?
Thanks Katie
I have seen a bug in Umbraco Forms that seems to be caused because Umbraco or ASP.NET has a default limit on JSON requests set to some relatively low value.
When a form is complex enough that the JSON request exceeds that default limit, it can cause errors.
I suppose the workaround would be to increase that JSON limit (if that is indeed what is causing the issue).
Open the network tab in Chrome developer tools and save the form. If you see a JSON request that responds with a 500 error, then that is a good sign the JSON is too long.
Typically, the response to that request will contain further details about the error (again, you can view that response in the network tab).
Hi Nicholas, I have done what you suggested and here is some info in relation to JSON. Does any of this make sense?

Hi Katie and welcome to our.
There is no limit on how many questions that you can have in your form.
Perhaps it could be a good idea to use multi step forms, if you have a lot of questions so it easier for the user to use.
Hope this helps,

Hi Dennis,
Thanks, that is making it easier, however I still reach a certain spot and it won't let me save, it says - Failed to Save Form - and it just won't let me add anymore once i reach this point. Is there anyway I can check what the problem is? Thanks Katie
Hi Katie,
One place to check for more information about why you can´t save the form are in the log files.
You can find the logs in the App_Data/Logs
Hope this helps,
/Dennis
is it possible that one of your field names is over the length limit? i think they have a limit of 255, but would need to check
Hi Fergus, no because I have tried just adding a field with just a number, it just won't let me add anymore fields

Thanks Nicholas, how do I find out if that is the problem and how do I increase the JSON limit? Thanks Katie

Typically, the response to that request will contain further details about the error (again, you can view that response in the network tab).
Let me know what you find out by doing that.

Not sure. There is a lot going on in the text. Here are some web.config changes you can try:
