Bobby,
It appears that Blogger thinks that the >-character at the end of the <html ….. > line is missing. I don't understand why that is happening, because I looked into the XML-file and the tag is really there.
Please check this first line carefully, and see that you did not accidentally removed some characters from it, or inserted a space. If this does not solve the problem, I suggest the following workaround:
- from your old template, copy the html-line, and paste it temporarily in a Notepad file.
- upload the new template
- replace the html-line from the new template with the html-line from the old template
- save
If that does not work, you could fall back to replacing only the skin of the old template with the skin of Underwater.
In the meantime, I will look into the template file. It puzzles me, as I downloaded this file straight from the Blogger editor, and did not modify it. So it should work properly when uploading. Arrgh, Blogs! ;)
