FREE control panels can be buggy or developers are not constantly working on it. It is always recommended to use paid commercial control panels in a production environment.
That said, there are several FREE control panels such as VestaCP, Webmin / Virtualmin, ISPConfig, and so on. that you can use.
The biggest advantage, in my opinion, with "CentOS Web Panel" is that it has a paid support that costs about $ 12 / year. and you get many other features, such as PHP-FPM support with multiple versions of PHP.
Go ahead and ask support to solve your problems … easy as …
Just a thought ….
