First of all glad to see that you’ve managed to upgrade the website and forum . Well done !
Same issue as this one from donx in the link below . Do not know which category it belongs to (webmin , virtualmin , or authentic theme ) .
To be more specific , “acl/?xnavigation=1” did not show the webmin users interface page but the csf module page .
With data-module / data-uri to csf instead of acl .
I found out two symbolic links in “/usr/libexec/webmin/acl” folder
Type: symbolic link to `/usr/local/csf/lib/webmin/csf/index.cgi’
Type: symbolic link to `/usr/local/csf/lib/webmin/csf/images’
I removed them and put a new index.cgi from webmin/acl on github . It seems to work now .
I do not know for sure if those symbolic links come from an update or not . I just wanted to let you know .
Thank you .
Operating system: Centos 7.9.2009
