I have been using K2 for many years. I am building a new Joomla site and I ran into this error that seems to be related to K2. It only occurs when I attempt to save a K2 item.

See the screenshot below. Does anyone have a suggestion how to fix this problem? Thanks in advance for your help!

I am using Joomla 3.8.1 on PHP 7.1.

do you have smart search plugin enabled? if so try turning it off and see if that helps

Thanks William. Disabling the Smart Search - K2 plugin seems to have resolved the problem. I'll keep testing and let you know if I find anything different but at the moment I am good!
