That number 1 is present in your articles and other modules too. Either site is compromised or files are modified somehow.
What you do is following.
1. Backup your website in full, files and database.
2. Download latest template version from our website. Extract it.
3. Delete your black_white template from your server.
4. Upload new downloaded copy to your server. See if 111s are gone if not proceed to next one. This means you have to replace joomla files too.
5. Re download and upload your files to your server so you have a new fresh files. Restore database from your backup database. See if 111 are still there.
Good luck and see you around...
