Horde Error when logging in ( Warning: fopen(/tmp/horde NUMBER.log): failed to ope n stream: Permission denied )

The most common reasons for this error are the following.

1. /tmp has wrong permissions(chmod 777 /tmp) 2. /tmp/horde_12345.log is not owned by the proper user/group (chown cpanel.cpanel /tmp/horde_12345.log) 3. /tmp/horde_12345.log has the wrong permissions (chmod 0644 /tmp/horde_12345.log)

Do the following to fix the above common problems... (as root)
chmod 777 /tmp
chown cpanel.cpanel /tmp/horde_12345.log
chmod 0644 /tmp/horde_12345.log


Note: Replace horde_12345.log by corresponding '.log'file.
