Defender Errors When Trying to solve issues

Hi there,

I've got Defender installed on my site and it says there are 3 errors: Prevent Information Disclosure, Prevent PHP execution, and update plugins and themes to the latest version. I try to 'solve' the issues by doing the recommended command, but it just errors each time. Can someone help me figure this out? The site is running well as ever, just want to keep this up to par.

Let me know when you can.

Thank You,

- Mark
