I was trying to find out what caused this issue, https://www.virtualmin.com/node/59402 , and I believe it was a setting in Joomla forcing HTTPS.
But on trying to test this solution if I click the “Only Update Renewal” button, the screen refreshes to the “Current Certificate” page, but nothing seems to happen after that.
In the miniserver.log is this referance, but I cannot find anything else relating to this issue, in any of the webmin logs.

Any ideas as to where I should start looking?
Many Thanks.
