Installation problem OS X El capitan

[atelier703]

Hello,
I have recently installed Stacey to built my architecture website. I have used cyberduck and copied all files in web directory.Then i have changed permissions of the "cache" folder and then run my website. And it seems that there is a code problem and i don't really know what to do. Perhaps someone could help me? I thank you in advance. Best regards.Bastien

I know how to fix this error but I need to be able to reproduce it on my laptop first.
What version of Stacey are you using and what version of PHP are you using?
