This error is shown when I load the site with php5 and the global variables stop working as well.
Warning: session_start() [function.session-start]: open(/tmp/sess_d61169214ef7571279ef183e6894bbc0, O_RDWR) failed: Permission denied (13) in /home/site/public_html/kernel/init/session_start.php on line 4 (line 4 is "session_start();")
This is what is required in my htaccess for my site to operated under php4. What do I have to change in order to get php5 to load the site properly?
755 only gives write access to the owner of the folder (ie root). Other users only have read and execute access. Your web server, Apache, is usually run as the Apache user, thus it can't write to the folder.
