Warning: Unexpected character in input...

[ashlibrooke83]

That is what the main page is saying at my album. It just came out of the blue. I had uploaded pictures the night before and everything was fine. But now I am getting a message saying,

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /homepages/16/d236411520/htdocs/cpg1416/index.php on line 35

Parse error: syntax error, unexpected $end in /homepages/16/d236411520/htdocs/cpg1416/index.php on line 865

Here is my page.

How can I fix this? Did I do something wrong?

Thanks.
