Help! Website Shutdown After Theme Upload

Hello All –

Currently receiving the following error message upon logging in:

Warning: require_once(/home/stepper587/public_html/wp-content/themes/yamidoo/functions/wpzoom/components/updater/framework-updater.php): failed to open stream: No such file or directory in /home/stepper587/public_html/wp-content/themes/yamidoo/functions/wpzoom/init.php on line 23

Fatal error: require_once(): Failed opening required ‘/home/stepper587/public_html/wp-content/themes/yamidoo/functions/wpzoom/components/updater/framework-updater.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/stepper587/public_html/wp-content/themes/yamidoo/functions/wpzoom/init.php on line 23

I uploaded a new template and I am now not able to access any part of the WP-Admin sites. My website is currently on Maintenance Mode.
