I’m having the same problem and have gone through the same process of changing the CHMOD to 755…keeping fingers crossed that eventually it will fix the problem…
I may be having a similar problem…I just got WordPress installed and working on my GoDaddy hosting account and figured out how to get to the admin panel. When I try to create a new post, I can type a title into the title area, but I can’t add any body text to a message. Weird…
