I came across the following post: https://forum.howtoforge.com/threads/error-on-log.94235/ I was able to resolve this issue on my server by checking the users (i.e., clients) with SSH access. You should look for the following directories and symlinks: Directories: var, dev, usr, run Symlinks: bin -> usr/bin, lib64 -> usr/lib64, lib -> usr/lib These directories and symlinks should be owned by the root user. If they are not, you can fix it with: Code: # chown -R root:root /var/www/clients/client2/web2/{var,dev,usr,run,bin,lib64,lib} Next, rebuild the jail with jk_init: Code: # jk_init -j /var/www/clients/client2/web2 basicshell coreutils editors !!! Note: client2 and web2 in these examples refer to my specific setup. Be sure to replace them with the actual client and website names used on your own server.
