Hi Amanda,
The error message displaying is:
Parse error: syntax error, unexpected '?' in /home/dannyiny/public_html/audiencebiz/training/wp-content/themes/profitstheme_11/functions.php on line 60
That's a straightforward syntax error in the theme's code. UpdraftPlus doesn't have any facility to alter themes, so the error must have come in via some other way; it's not related to installing UpdraftPlus.
If you like, you can email me a copy of the theme file - audiencebiz/training/wp-content/themes/profitstheme_11/functions.php - and I can send you back a corrected version. Or alternatively let me have your FTP or WordPress logins (email to contact@updraftplus.com).
