I have the following messages:
"The CTools CSS cache directory, sites/default/files/ctools/css could not be created due to a misconfigured files directory. Please ensure that the files directory is correctly configured and that the webserver has permission to create directories.
warning: realpath() [function.realpath]: SAFE MODE Restriction in effect. The script whose uid/gid is 175774/175774 is not allowed to access /f5//public/sites/default/files/ctools owned by uid/gid 25000/25000 in /f5//public/includes/file.inc on line 182."
I have tried many combinations of permissions using Ubuntu's gui, nautilus. The permissions seem to change but I'm not sure what I should have.
I don't really know what permissions or ownership should be assigned or how to do it.
