Ajax and Resulting Blank Screens

When clicking certain areas I am experiencing resulting blank screens. I am also experiencing resulting blanks when ajaxui# comes up in my URLs. When going to admin - settings - configure ajax – that screen is also blank. tells me to configure below but no window shows like i’ve seen on the forum here.

all directories seem to be 755 as stated in install guide.

my eyeballs dont work. changing directories to 775. hope that fixes the issues i’m having.

This seems to have fixed my issues.
