are you sure the upgrade is the reason ?

Hi all,

I upgraded to 4.0.3 from 4.0.

b2evo is running on apache2 web server.

Any idea's?

Ok, the following assumes that you can manipulate the owner and group of the directories and files. I have only used once an interface like cPanel -hence I sort of remember ownership/group may be set/modified- but I usually apply modifications from the GNU/Linux command shell as root or super user.

If Apache web server is running on GNU/Linux Red Hat (and derivatives like CentOS), the default user is: apache and default group is: apache

If the Apache web server is running on GNU/Linux Debian (and probably Ubuntu, as well) the default user is: www-data and the default group is: www-data

Setting chmod 0777 (-rwxrwxrwx) is equivalent to allowing the owner, group, and other (users) permission to read, write, and execute. I would not want to allow other (users) permission to write to the directory(ies) hence I would set: chmod 775 (-rwxrwxr-x) for directories and chmod 774 (-rwxrwxr--) for files --at the very least.

Please see [url=http://www.askapache.com/security/chmod-stat.html]Chmod, Umask, Stat, Fileperms, and File Permissions[/url]

Note that tighter security is possibly if the owner/group of the files is set to the Apache web server as indicated initially.

Good luck!

Thanks, checking out right now.
