When adding sieve to a valid hestia error 500 web mail

Community Support Install & Set-Up

Hi everyone, I used this theme to add sieve, but got error 500 when logging into the webmail Roundcube. Rolled back system login to web mail returned. Perhaps someone came across this, I want to add sieve to the installed system and before I did it without difficulties, why now I don’t understand so much. Tell me who knows where to look to fix it, I reviewed all the logs but never saw why the error, the domain is available, the logs of the panel, mail, nginx without errors, in the/var/log/roundcube itself is also empty).
I even used ‘v-update-sys-hestia-git hestiacp main install’ and updated to version 10 alpha, but error 500 remained)

Hi,

The install_sieve.sh script should work. To find the cause of the 500 error, we need the log. A 500 error must leave an entry in the logs.

Now I’ll run the sieve script again, but I searched the logs when webmail returned error 500, which log to watch?

If you are using Nginx only /var/log/nginx/error.log and /var/log/nginx/domains/webmail.YourDomain.error.log

Yes, thank you very much!
It turns out that when using the sieve installation script, directory rights fly off.
