I have two domain names hosted on one PAYH account, which was a 'preview' one established some years ago. The PAYH account appears to have 500 Mbyte disk space allocated, but one domain has a limit of 250 Mbyte and the other 50 Mbyte. I would like to increase the first one to, say, 450 Mbyte but can't see how to do that.
There is an item in a FAQ post dating from 2008 explaining how to do it, but the layout of the Plesk interface has changed since then and I can't see how to do it now.
