Hi! I migrate my ispconfig panel, from my old server to new, all the data passed server to server from ssh and root permissions. Because of this, all folders in / var / www were with root privileges. I switched to www-data, yet things are not going well, there are some pages that follow showing me 500 error or having strange problems. That's when I realized that each folder of each web, has associated permissions and number of customer web. How could establish those permissions again automatically? Is there any way? thank you!
