Our website is planetinmotion.org
In order to make a backup I tried to install the plug-in "wordpress backup to dropbox". I couldn't install it as Wordpress was requesting FTP username and password and then telling me that it couldn't create the directory.
I looked on websites for support. They said it was a problem of files permissions. So I decided to change all my files to 777 permissions on my ftp server.
What a donkey! Now I have this error message: 500 Internal Server Error when I go to my website and to the wordpress cpanel.
What should I do?
Thanks a lot.
