404 error

Hello,

I’ve been happily using the Polylang plugin, but for the past week, I’ve been struggling with an issue I can’t resolve. I’m using the Flatsome theme, and when the Polylang plugin is active, the 404 page doesn’t work properly.

I get the following error: “Block 616 not found.”
I’ve created a custom 404 page for missing pages, but it doesn’t work when Polylang is enabled. When I deactivate the plugin, the problem disappears completely.

The page I need help with: [log in to see the link]
