QC syntax error, unexpected T_STRING

I’m getting the white screen – turned on debug and got this message:

syntax error, unexpected T_STRING..site info…//wp-content/advanced-cache.php on line 2

here is the upper half of the file (not sure if line is starts from beginning or from beginning of code info)

any help is MUCH appreciated.
