Google Search Consult -- 2

I'm looking for assistance with optimizing my website to clear out some of these error messages. I'm NOT looking for month to month seo services. Please note that my website is NOT on WordPress and I do not use cPanel. My site is a static site that is ran on my server that I edit my own files and upload them to my server. Please specify exactly how you think you can assist me as I am familiar with coding and Google search consult. I will not reply to people that have automatic replies to jobs for authentic responses to my query.
