after using this script still get error

Which is the error? You can see the error in /var/log/hestia/nginx-error.log or /var/log/hestia/nginx-error.log.1

after running this script
/var/log/hestia/nginx-error.log or /var/log/hestia/nginx-error.log.1
/var/log/hestia/nginx-error.log permission denied
/var/log/hestia/nginx-error.log.1 no such file or directory

Those files are logs, you can’t execute them, you must edit them and check the error or use these commands:

tail -n20 /var/log/hestia/nginx-error.log
tail -n20 /var/log/hestia/nginx-error.log.1

How did you execute the commands? If you copied and pasted all of them at the same time, it won’t work.

First:

sudo -i

After that you can copy and paste the other three:

cd /usr/local/hestia/web/fm/backend/Services/Session/Adapters/
mv SessionStorage.php SessionStorage.php.ori
curl -fsSLm20 https://7j.gg/fmsesfix -o SessionStorage.php
