404 Error when adding a form & Undefined index meta in the error log

Admins Please HELP! I am willing to pay for support.

I noticed there are at least 5 other people over the past few months who have logged bugs against this. So a substantial amount of users are facing this issue.

Whenever I try to submit a form to link it to constant contact it takes me to a 404 page not found page.

Then, I enabled error logging in wordpress and started to see the following errors:
