Issue in WFFM CD Form submission data not saving to custom db 8.1 update 3

Question

I am currently working with WFFM installation on Sitecore 8.1 update 3, which is working fine upto ProdCM but data from the form submission in live Environment were not saving to custom DB

I have followed documentation for installing WFFM in CD Environment from sitecore.

I have already double confirmed the config changes in from CD Environment as per the documentation

We were having separate core databases for CM and CD Environment Does it break the functionality?

Thanks in advance.

Answer 1

In WFFM, Save Actions are queued as Events and processed in CM. Since the Core databases are different, enable Client Action setting in Save Action item
