I don’t know what you did, but all debug options were set to false. After changing them to true, the following error message was generated:
Warning: require_once(/home/vol14_7/epizy.com/epiz_25978019/htdocs/wp-content/plugins/updraftplus/options.php): failed to open stream: No such file or directory in /home/vol14_7/epizy.com/epiz_25978019/htdocs/wp-content/plugins/updraftplus/updraftplus.php on line 219
Fatal error: require_once(): Failed opening required ‘/home/vol14_7/epizy.com/epiz_25978019/htdocs/wp-content/plugins/updraftplus/options.php’ (include_path=‘.:/usr/share/pear/’) in /home/vol14_7/epizy.com/epiz_25978019/htdocs/wp-content/plugins/updraftplus/updraftplus.php on line 219
So it seems that the updraft plugin was corrupted.
You can disable it like this and restore access to your website:
After that, you can try to reinstall it.
That said, I would recommend against installing Updraft. Script time limits and file size limits prevent such scripts from working correctly here, and creating the backups uses a ton of CPU and IO power and is frequently the cause of repeated suspensions for hitting those limits.
