You have cformsII version 14.13.3 installed. The CFDB support is buggy in that version, so please update to 14.14.
Thanks for writing back and for your support!
Unfortunately, I did upgrade to 14.14 this morning, but when I did, all of the forms on my site (there are tons) stopped working. All of them. I rolled it back to 14.13.3 and prefer to keep it that way for now because I don’t have time to try to figure out that issue. I have experienced zero bugs with 14.13.3.
Are you willing to tell me how do I activate cformsII support on the CFDB plugin?
Please see the last two posts at https://wordpress.org/support/topic/form-disappears-after-upgrading-to-14-14
You do not have to do anything except installing CFDB from https://cfdbplugin.com – its default setting is to record cformsII form submissions. Please check if you have the right CFDB installed (NOT CFDB7).
