The site is experiencing technical difficulties

Hello, i have polylang installed and Post Type Builder from Themify, i created a taxonomy, a post type, i filled out the post type fields and published it. When i go to see the page i get that error message “The site is experiencing technical difficulties” if i disable polylang, it shows no error and now it shows the fields info. There is an incompatibility with your plugin. I checked “Custom post types and Taxonomies” option on Polylang and unchecked the boxes, but still shows the flags in the fields

I will leave the same message on Post Type Builder forum, but i hope if you can solve it. thanks!
