Hi,

My buddy upgraded his website. It failed. It was several months ago.
Recently he asked for help.

I followed the article and uploaded all the files that I downloaded from your site.
Nothing changed.

I have disabled all plugins, no change.

Other pages also post errors either at the top or bottom of pages.
