I get “503 Service Unavailable” on GCP after one-week work on customizing a site…
I have no access to the panel, no idea where phi.ini is, don’t know where to look.

WTF?

Look in the files

PHP ini would be in one of these locations with the paths slightly different depending on version
/usr/local/lsws/lsphp73/etc/php.ini
/usr/local/lsws/lsphp73/etc/php/7.3/litespeed/php.ini

Thanks for your reply, I tried everything but I’m still down:
-increased disk space, cleared error logs, increased mem _limit in php, even upgraded the cpanel to 1.9 and restarted everything

I am still at the same point, 503 error, could be DNS related - will look into that, but I think it still has to do with the resources on server.

Got the Cyberpanel back up, and it’s showing disk over capacity (!?)

I increased disk size and cleared all logs in /usr/local/lscp/cyberpanel/logs/ what else can I do here?

this is due to the cyberpanel default package you will want to modify it

Thanks for your support @whattheserver.
I was able to restore the site through a combinations of tweaks and using a backup.
Still couldn’t figure what exactly caused the 503, but at least I gained more insight in using Cyberpanel.

My pleasure. Glad to hear you got things working.

If you run into issues in the future tailing the error logs for the control panel or litespeed/openlitespeed is the best way to debug.

For example:
tail -f /usr/local/lscp/cyberpanel/logs/error.log
or
tail -f /usr/local/lsws/logs/error.log

Hello.
in CyberPanel 2.0, I no longer can use/restore backups.

Any suggestions would be greatly appreciated.

Thanks.

Are your backups in /home/backup/?

Yes.
Backup function works and produces current backups, file manager also works and I can upload old backups, however nothing shows in cyberpanel when I try to do restore.

Fresh install, cyberpanel 2.0, I haven’t done any change or mod on it.
