EDIT - the <!doctype> isn't on the first line either - not sure if that matters
Most likely there is an issue with "/includes/templates/zenn/common/html_header.php". Possibly the upload was corrupted... But a more likely cause is: the file was opened with a text editor, edited, and not saved using UTF-8 without BOM (the without BOM is very important). If this issue is present in the theme files, one will want to review the character encoding used in all of the theme files ("/includes/templates/zenn/*"), in the define pages ("/includes/languages/<your_languages>/html_includes/*"), and any core Zen Cart files which have been modified.

One will need to use a text editor supporting UTF-8 without BOM (such as NotePad++ or one bundled with an IDE) to edit and save files with the correct character encoding.

This does not look like an issue with CEON URI Mapping. I did notice the theme is a commercial theme purchased from themeforest... If the OP needs additional help fixing the theme, I would recommend they contact the author of the theme for commercial support.
