Remove unused php Version from Webmin/Virtualmin

Hi, we have 4 different php versions installed (think they came with the standard updates…). How can I uninstall the once we do not need anymore… have not found a setting for this in the backend…
thanks.

remove unwanted packages first, then re-check virtualmin configuration

So If I want to get rid of php7.1 I search for php7.1 in the software package menu and remove every module it shows for php7.1? There are k-o and p-t classes… is it safe to uninstall them or do I have to take care for any dependecies (all my domains use php7.2)?

Ok, for anyone having the same question. It worked like described above…just click purge and remove dependencies before uninstalling all php7.1 modules…
