Thanks for the suggestions.
Actually, I had problems with installing when i just uploaded (Think many of the files were 644), so i did a chmod 777 on the entire thing. WP redid permissions for some of the files during the install, so I guess those are ok, but I was wondering about the rest? Like the wp-includes directory for example… (and all the files within) What’s the difference between directory and file permissions anyway? What do I have to keep at 777 and what can i restrict to a lower level?
