I'm working on a local dev site. Everything was OK, but then I upgraded to 3.1.1, and now I'm having problems in the admin section...?!
It seems that every time I do something significant in the admin area: create a page, delete a page, etc. The screen goes blank.
If I then press the browser's back button I can see the previous view, but then have to refresh to see if the action has been carried out.
It works every time, but this is very frustrating. Is this a documented problem & is there a fix?
I've even started over from scratch with 2 new installations, but get the same issue in each. There are no plugins installed, just my basic starter theme that I use for all my projects (ie. something that's never caused problem before).
Can anybody help?
