Thank you very much for your answer.

Hello, I'm sure the cause of the problem is within KeyHelp Server operating system + version Ubuntu 20.04 (64 bit) Server virtualization technology used KVM KeyHelp version + build number 22.2 (Build 2838) Problem description / error messages I had to manually install version 12.0.2 of the ioncube ...

Is there a way to restrict access to the whole keyhelp panel, by limiting access to a single IP address.
PS. I would like to forbid access to attackers.

Thank you!

Thank you very much I will go for the OS upgrade option.

Thanks for your answers, I will try to do it.

But it will be really useful to integrate an option to the KeyHelp panel that will simplify the operation of upgrading MariaDB.

Unfortunately since it's a production server I can't take this risk.
My OS is Ubuntu 18.04.5 LTS (with MariaDB 10.1)

Please upgrade MariaDB at least to version 10.2

Because several PHP scripts are no longer compatible with MariaDB 10.1

Thanks,

Hi,

It will be a great plus for KeyHelp if you add an option for installing and managing ModSecurity using the web interface of your panel.

PS. Thank you very much for your good work!

Please update ionCube PHP loader to 10.4.1 (or latest), this version adds the long awaited support for PHP 7.4

Thank you

Thank you very much Alexander, it's working perfectly.

One last question:
Will this modification be integrated in a fix in the next version? Or do I have to do it manually?

There are no errors in the MySQL log, either when adding a new email address, or during authentication. root@vps:~# tail -f /var/log/mysql/error.log And as for performance, it's a VPS KVM with Ubuntu 18.04 (64bits), 1Gb RAM and 20Gb SSD disk space. PS. The 20.1 update didn't solve my problem ...

Will the next KeyHelp update 20.1 fix my error? Or do I have to reinstall the whole thing from scratch? This is obviously one of the errors below: - Dovecot not being able to connect to MySQL - Dovecot's MySQL privileges are incorrect - The problem lies in the creation of a mail account on the ...

I restarted MySQL and Dovecot and Postfix, and also the VPS, without success it doesn't fix my problem. Below the content of /var/log/mysql/error.log root@vps:~# cat /var/log/mysql/error.log 2020-05-10 13:19:40 139786339948288 [Note] /usr/sbin/mysqld: Normal shutdown 2020-05-10 13:19:40 ...

Isn't there a script or command from KeyHelp, to check and fix Postfix/Dovecot integration with MySQL?
That I can fix this error without having to reinstall everything.

Yes, because my WordPress sites are working properly.
