My permission page has gone blank
 

Hi Guys,
I messed up my site last night when using impex, so I decided i wanted a clean install - wiped the databases but kept all the files (this could be my problem) did a new install - everything works but this happens on all the permission pages, I have installed it twice now and keeps happening, any ideas what is going on?

Thanks,
Chris
