Problem Resolved: Note This was a hosting issue. I have a vps and there was a ModSecurity rule triggered on your website. ModSecurity is an Apache module which works as a web application firewall. It blocks known exploits and provides protection from a range of attacks against web applications.
It uses sets of rules to identify the threats, and these rules are triggered when the module discovers a match. ModSecurity has conflicts with some scripts and plugins which may result in false-positive blocks.
Note: this also kept me from updating listing records!
IF THIS HAPPENS TO YOU ASK YOUR HOSTING COMPANY TO WHITELIST RULES 212280 and 211650
Thank you guys for trying to help me fix the issue. I found by researching Ninja Forms Forums that someone else had a similar problem and my hosting company figured out it was a apache firewall issue.
