Hi Jan,
What does your last “Yeah” mean? Did you manage to solve something?
I logged in to your site, activated the plugin, checked the plugin settings, and found everything okay there.
Then I went to the YARPP settings page, I didn’t change anything there, I just saved the YARPP settings again with the “Save Changes” button, but I got this message: “There has been a critical error on your website. Please check your site admin email inbox for instructions.”
I didn’t have access to your site’s log file, you should see what is the cause of this YARPP settings page error on your site.
I’m writing another email with private information.
Peter
