Your robots.txt file is missing or unavailable.

Your robots.txt file is missing or unavailable. No matter what I try I can’t get rid of the error, I’ve tried resetting the robots.txt file through AIOSeo, but that didn’t work. I’m running WPS Hide Login not sure if that’s causing an issue. But I’ve tried uninstalling the app & it didn’t make a difference. Enable custom robots is off. Clicking on “open robots.txt” opens the file… so it exists
