I was referring to the 2 config files of photopost need 666 permissions. You do not change any of the core php files to 777 permissions. You can read the install instructions under the support tab in our header for more specific information.
You can change your servers php through your php.ini file but you may need to ask your host.
I am merely saying to do a backup you need the proper path to mysqldump and the proper path to a directory you made that has 777 permissions to backup to.
You really shoulud update soon. I am getting read to put out another update.
