My ISPConfig 3 run normally. Just few days ago it show only blank page on admin. But the client sites still working fine. I try to look at the apache error.log but see nothing write in there. But I still see request in access log.
Blank page is often PHP error. Check PHP logs and increase PHP verbosity. Also, https://www.howtoforge.com/community/threads/please-read-before-posting.58408/
Who or what said that? Restore the missing file from backups. It seems to me ISPConfig can not work without that file. I believe that file is created by the ISPConfig installer, so it can not just be copied from the installation package.
It didn't fixed. The problem is I can not see the log. So I don't know how to debug. Where can I see the ISPConfig Log?
ISPConfig can indeed not work without that file, but its for the server part and you get a 500 error in the interface, so there must be other files missing too. Or... you did not run the test script as root, which will produce a wrong result as only root and ispconfig user can access that file.
Requests for ispconfig UI are logged in the global apache error.log, there is no separate log for PHP failures in the UI.
Actaully it is not the real problem. The because at the moment I run your script without root that why it say missing that file. when I run it as root the file is there. So now I think I just want to see the log but I can't
Try, as root, Code: tail -f /var/log/apache2/error.log Yes, installing PHP 7.3 breaks ISPConfig, unless you turn default PHP back to PHP 7.0. https://www.howtoforge.com/tutorial...bian-default-php-back-to-the-original-version From now on, do not let your developers install stuff as root on servers you maintain. I fixed all mysterious crashes and errors by new root password and not telling anyone what it was. I wrote the password in sealed envelope which I stored in fireproof safe, and informed everyone I will not fix anything if I discover that envelope is opened.
Thank for advise but nothing I can do. I just another developer. But if I managed to fix this I won't fix it again in this such of case

Is the log you posted from the time you got the blank page or after that? You need to look at the log when the error happens. And, please post logs in CODE tags to make them more readable. You can examine the complete log file with Code: less /var/log/apache2/error.log You could also post the output of https://www.howtoforge.com/community/threads/please-read-before-posting.58408/ script just to make sure. And please post it in CODE tags.
And if this is your company server and you're not that familiar with Linux, then you might want to contact Florian from ISPConfig Business support to fix this by remote login: https://www.ispconfig.org/get-support/?type=ispconfig
You can try it: Code: cd /tmp wget http://www.ispconfig.org/downloads/ISPConfig-3.1.13p1.tar.gz tar xvfz ISPConfig-3.1.13p1.tar.gz cd ispconfig3_install/install php -q update.php But I guess it will not help as ISPConfig is probably not damaged here, what's damaged is your PHP environment outside of ISPConfig which causes ISPConfig to not work. So probably redoing the webserver and PHP installation steps from the original tutorial that you used to install ISPConfig before you run the update steps I posted might help.
