Your error message is:
Parse error: syntax error, unexpected ‘<‘ in /home/vg007web04/53/56/3015653/web/wp-content/themes/gridspace/functions.php on line 151
You will have to look at your function.php file. This is likely to be a stray < within php tags. If you had an extra < in text, it might wreck you theme but you would see something. Perhaps you have forgot to quote stuff in an echo line.
google site verification, if that is what you are talking about, goes in a meta tag in the header. But this a php problem.
I fixed it… just reuploaded via ftp the function.php file of my theme.
