Can the editing open_basedir impact the server operation?

My question may sound stupid, so I'm sorry in advance. But can a change in the entry in a particular website of open_basedir option affect the performance of the entire server, or the inability of Apache to restart. My question is because my test website is located on a server with production sites. And I would not want to make these changes without initial consultation. My problem was described in this post: https://www.howtoforge.com/communit...ifferent-user-directory-in-ispconfig-3.83621/ and the problem seems to be related to open_basedir, so I think I need to add a new path to the open_basedir site parameter. People who know how this option works specifically, please respond to this post. Thanks in advance.

 

Thank you so much.
