We are trying to migrate from a 11.5 to Plesk 12 on Centos 7, it shows the following warnings:
python is not supported
Or like this:
asp is not supported
miva module is not supported
Apache ASP support and Apache mod_python module cannot be installed via Plesk Autoinstaller. The mentioned modules are not supported on Centos 7. This issue is already reported to Plesk Service Team with internal reference id #PPPM-1968 and it will be fixed in one of the next updates.
There is no workaround at the moment.
