Can you get to the dashboard? If so you can try to turn on the full error report so you can see where the error is generated. Otherwise you can try to rollback the page to an earlier version without that block.

I can see the full error report. I see that at 15:44 on June 14th there was an error loading/locating a file [home.php] and produced an error code. Prior to that there is an error regarding a form over thirty minutes prior. I think I have the full log but can you talk me through making sure.

here is a log file

I meant go into the Dashboard -> System & Settings -> Debug Settings and check the box for "Output error information to site users" and select the radio button for "Show the debug error output" so when you go to the front end you can see where the error on the page is coming from.

I have done this and here is the resulting file. However in reading through it I seem to be missing the hint to why my index page will not load. I can't even locate the file home.php on my server so I am very confused about how I will repair it.

This doesn't appear to have anything to do with a file called home.php, this appears to be a missing image file for the "simple_thumbnail_list" Custom Template for the PageList block. So, I would either check your pages that are supposed to be populating that PageList and replace the missing image, or go into /­home4/­sheridc9/­public_html/­packages/­fundamental/­blocks/­page_list/­templates/­simple_thumbnail_list/­view.php line 42 and change it to
