I did recently migrate an CPANEL backup to Virtualmin, and it went good the wordpress site is working as it should. I had only to change the username and password on wp-conffig and activate SSL. I just cant find the wordpress installation on the INSTALL SCRIPTS list on Virtualmin.
When scripts are installed via Virtualmin’s Install Script module, they are listed (and can be updated and uninstalled) via the installed scripts tab.
However if you manually install or import a WordPress install then it will not be listed in Virtualmin’s Install Script module even though WordPress will operate normally in all other respects.
