I recently had to completely erase and reinstall Webmin and Virtualmin on a machine due to a 3rd-party webmin module patching the interface and making some modules inaccessible. However, after I re-installed, the Virtualmin interface is completely missing (i.e. the tab, in the left panel, is gone). It's as if only Webmin is installed and not Virtualmin. Can the Virtualmin interface/panel enabled through Webmin configuration (and is there something I'm missing)? How might I be able to restore Virtualmin to the way it was?
EDIT: I found that what caused the problem: under "Webmin"->"Change Language and Theme" I didn't have it set to the global theme, "Virtualmin Framed Theme".
