I just did an update from 184.108.40.206 to 220.127.116.11 with the connect manager. Since then the website is unreachable. It sometimes works if I refresh multiple times but I get an error 500 most of the time.
I checked the log and it seems the cronjob is spamming this error:
2017-11-02T12:37:28+00:00 ERR (3): Warning: shell_exec(): Unable to execute '/bin/sh '/html/my-shop/cron.sh' 'cron.php' -malways 1 \> /dev/null 2\>\&1 \&' in /html/my-shop/cron.php on line 67
The host is a shared hosting solution so I am not able to see apache or nginx logs. Maybe the cronjob failing is causing the host to shutdown further connections ? How can I fix this issue?
