@paul2009 Thank you so much for your feedback and response. This is very helpful.
I was misinformed about these 'warnings' and told they were errors when I had reached out asking for help as to why a few of my pages are not loading, despite looking like they are linked properly.
I did hire someone through SquareSpace but they had me pay them directly, you mentioning this 99d is the first I have heard of that. So unfortunately I am out this money, since I already reached out to the owner of the company as well.
I am really just looking to potentially hire someone else to help me finish these last few items so that I can completely launch my site.
Very grateful for your response.
