We have upgraded every plugin and WP core and are only receiving this error when we are on the admin screen of this plugin. This is preventing us from creating filters. Please advise, we are in a time crunch to complete a project.
Welcome to our forum.
I am not sure why this conflict happening, can you please check which plugin use Iris color picker script, and you can disable to check the issue.
If possible please send me a temporary admin access to your site, i will check the issue.
