The error is in your database.
It appears GRAMPS to write the footer text of your webpage, but this footer contains some symbols that python is not able to print, and it raises a UnicodeDecodeError.

So please, have a look at the text of your footer, and remove the footer, then try again. Then add the text again and retry.
Normally it is impossible to add non-unicode symbols to notes in GRAMPS, it would be interesting for us to know how this bad symbols where added to the database.
