Can’t add any more fields in my ninja forms

Hi there,

I am having trouble while adding new fields in my ninja forms (37 active fields at the moment), indeed when adding a field I don’t see it appear in the preview and when trying to publish the process would just take for ever (literally for ever…) and just not publish the changes.

I am trying to build a complex multi-columns form where some fields comes with +200 options (countries or languages).

Here is the form I am trying to recreate : https://2m.com.au/translators.html

I have been in contact with the NF support but they haven’t been able to assist with this. Hopefully someone here has been through the same issue.

Thanks for helping

Regards
Thomas
