@whooami, that answer u gave is correct but I am not sure why we need to change the wp content and themes folder to 777?
I had wp-content and Themes folder set at 755 and files needs to be edited had 644 when I was at my previous host and I never saw any issues. But after moving to a VPS I cant work with 755 and 644 I hv to go with 777 and 666?
Any idea why?
