Unwanted text showing at top

It looks like it’s a script file that wasn’t properly inserted. My guess would be it’s in your header.php file.

It looks like it’s for google analytics. I think it’s missing the opening < before the word “script”.

possibly not even related to the wordpress blog on your site, but rather an error in the header of the existing start page (index.html ?)

the same google analytic code seems to be properly inserted into the blog part of your site.
