Blacklisting Keywords Stopped Working After Updating To PHP 7.3

Hi. I am utilizing this method to block spam on multiple websites: http://www.chronoengine.com/faqs/55-chronoforms/cfv4/cfv4-anti-spam/2626-how-can-i-ban-some-words-from-posts
​
I had this working for Chronoforms v4, v5, and v6 on PHP 7.1.
Once I updated to PHP 7.3, this stopped working on all forms. Now all the forms submit even with the blacklisted keywords when they should return an error message without submission.
​
Any thoughts on this? Should something in the php code be updated? Or does something need to change in the Chronoforms setup? Any help is appreciated!

Hi kko,

The code in the FAQ still looks OK. Please try setting your Site Error Reporting temporarily to Maximum and see if you get any more helpful error messages.
