problem with wp control

Hello

My website was off for few hours. So I contacted wordpress support. They removed wp-control from my website. Now my website is one but my client can’t logg in logg out.
Wordpress support suggested to send you this message :

“Warning: require_once(/srv/htdocs/wp-content/plugins/wp-crontrol/vendor/autoload.php): failed to open stream: No such file or directory in /srv/htdocs/wp-content/plugins/wp-crontrol/wp-crontrol.php on line 45 Fatal error: require_once(): Failed opening required ‘/srv/htdocs/wp-content/plugins/wp-crontrol/vendor/autoload.php’ (include_path=’.:’) in /srv/htdocs/wp-content/plugins/wp-crontrol/wp-crontrol.php on line 45”

Can you do someting ?

Cheers

Clément
