I got those errors when I was trying to install dolphin 7 by myself... I thought there must be an easier way... I took a look around and I thought what is "Softaculous"? I took a look and their is an auto installer in there for Dolphin 7 that you just put in your info and where you want it and...
Any chance you can help me fix these paths??
