Server modifisering

Hi, i just have some problems on my server and i need to fix it now.

1) Configure the following command on crontab every minute:
cd /home/admin/web/pornsly.com/public_html/admin/include && /usr/bin/php7.4 cron.php > /dev/null 2>&1

2) Add the following block to domain nginx config for preventing direct access to your video files:
# protect videos from direct access
location ^~ /contents/videos/ {
root /home/admin/web/pornsly.com/public_html;
limit_rate_after 2m;
internal;
}

3: Error /%ROOT%/admin/data/system/cluster.dat Write permissions required

4: PHP Memcached module is not installed

5: Warning /%ROOT%/info.php Suspicious file found

6: Notification Youtube-dl Youtube-dl library is not found
