I have issue at my page’s preview when I use Polylang plugin and then after I am unable to edit page. I am using Pro Theme at my website. My English page loads fine and I am able to edit the page normally but when I create page with Pro Editor at other language then I have below error message.
“The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.”
Hoping for reply.
